CMIS 141 Homework 2

Homework 2
Before attempting this project, be sure you have completed all of
the reading assignments, hands-on
labs, discussions, and assignments to date.
Design a Java class named Polygon that contains: A private int
data field named numSides that defines the number of sides of the
polygon. The default value should be 4.
A private double data field named sideLength that defines the
length of each side. The
default value should be 5.0.
A private double data field named xCoord that defines the x-
coordinate of the center of
the polygon. The default value should be 0.0.
A private double data field named yCoord that defines the y-
coordinate of the center of
the polygon. The default value should be 0.0.
A private double data field named apothem that defines the
apothem of the polygon.
The default value should 5.0.
A private double data filed named perimeter that defines the
perimeter of the polygon.
The default value should 20.0.
A no argument constructor that creates a Polygon using the
default number of sides,
default side length, default x- and y-coordinates, and the default
apothem.
A constructor that creates a Polygon using a specified number of
sides, side length, xand y-coordinates and the apothem
Getter and setter methods for all data fields
A getArea() method that returns a double value representing the
area of the polygon.

(Note the area of a regular Polgon can be calculated from ½ *
Apothem*Perimeter)
A toString() method that displays the number of sides, side
length, x-coordinate, ycoordinate and apothem values in String
format Be sure your code compiles. You should use the command
prompt and not a GUI for data entry and
display.
Write a Java test program, named TestPolygon, to create 5
different polygons representing the 5 test
cases you just created. When creating the five polygons, create
one using the no argument constructor.
For the remaining four, feel free to use any number of sides, side
length and x-, and y-coordinates and
apothem that are not equal to the default values and not equal to
each other. For each of the five
polygons, call all of the methods and display the results. For
example for a Polygon with 3 sides, side
length of 2.0 and x-coordinate and y-coordinates of 1.0, and
apothem of 1.0 the following test data may
result:
***Output***
toString(): (numsides=3, sideLength=2.0, xcoord=1.0,ycoord=1.0,
apothem=1.0)
getNumSides(): 3
getSideLength(): 2.0
getXCoord(): 1.0
getYCoord(): 1.0
getApothem():1.0
getPerimeter(): 6.0 1 getArea(): 3.0 Document your test cases in
the form of table with columns indicating the input values,
expected
output, actual output and if the test case passed or failed. This
table should contain 4 columns with
appropriate labels and a row for each test case. An example
template is shown below. Note that the
actual output should be the actual results you receive when
running your program and applying the

input for the test record.
Keep in mind, for five Polygons, you will have five different
output results. Also, note there is no
requirement to actually draw a Polygon.
Example test cases:

Constructor:
numsides=3
sideLength=2.0
xcoord=1.0
ycoord=1.0
apothem=1.0 Expected Output
** Output ** Actual Output
** Output ** toString(): (numsides=3,

Homework 4
Write a Java program the displays the State bird and flower. You
should use your IDE for this exercise.
You should also use Java classes to their full extent to include
multiple methods and at least two classes.
The program should prompt the user to enter a State and print
both the State bird and flower. The user
should be able to enter a State without worrying about case. (e.g.
Users could enter Maryland,
maryland, MARYLAND or any other possible combination of
lower and upper case characters. States
may also contain leading and trailing white spaces. Hint: Store
the State information in a multidimensional array. The program
should continue to prompt the user to enter a state until “None” is
entered. After all States have been entered by the user, the
program should display a summary of the
results. You will need to do some research to find the State birds
and flowers. Here is a sample run:
Enter a State or None to exit:
Maryland

Bird: Baltimore Oriole
Flower: Black-eyed Susan
Delaware
Bird: Blue Hen Chicken
Flower: Peach Blossom
None
**** Thank you *****
A summary report for each State, Bird, and Flower is:
Maryland, Baltimore Oriole, Black-eyed Susan

CMIS 141 Project 4 This programming project

Project 4
This programming project involves writing a program to manage
a student database. The interface to
the program should be a GUI that looks similar to the following:
A combo box should allow the user to select one of the four
database actions shown. The database
should be implemented as a HashMap, with the ID field as the key
and a student record consisting of a
name and major as the value. The operation should be performed
when the user clicks the Process
Request button. If the user attempts to insert a key that is already
in the database an error message
should be displayed using a JOptionPane message dialog box. If
the user attempts to delete, find or
update a record that is not in the database, a message should also
be displayed. After each successful
operation is completed a JOptionPane window should be
displayed confirming the success. In the case
of a successful Find request, a window should pop up containing
the student's ID, name, major and
current GPA. When the user selects the Update request, the
following JOptionPane windows should be
displayed to gather information about a course that has just been
completed: 1 This program must consist of two classes.
1. The first class should define the GUI and handle the database
interactions.
2. The second class named Student, should define the student
record. It must have instance
variables for the student name, major and two variables that are
used to compute the GPA. A
variable that contains the total number of credits completed and a
second variable that contains
the total quality points, which are the numeric value of the grade
received in a course times the
number of credit hours. It should not contain the student ID. The

class should have the following
three methods:
a. A constructor that is used when new student records are
created. It should accept the name
and major as parameters and initialize the fields that are used to
compute the GPA to zero.
b. The second method courseCompleted should accept the course
grade and credit hours and
update the variables used to compute the GPA. It will be called
when an Update request is
made.
c. The third method should override toString and return a labeled
string containing the
student name, major and GPA.
Finally when a student has not yet completed any course, the
GPA should be displayed as 4.0.
Braces use K&R style. In addition the following design
constraints should be followed: Declare all instance variables
private
Avoid the duplication of code
Also any exceptions thrown by nonnumeric inputs should be
properly handled Test cases should be supplied in the form of
table with columns indicating the input values, expected
output, actual output and if the test case passed or failed. This
table should contain 4 columns with
appropriate labels and a row for each test case. Note that the
actual output should be the actual results

you receive when running your program and applying the input
for the test record. Be sure to select
enough different scenarios to completely test the program.

state of the turtle. For
operations. should draw a rectangle beginning at the initial
of t, and should leave t with the same position
Do not make any assumptions about the initial
full credit you must use a loop for repeated Question 11b
12 points
Write a function named panels() that uses turtle graphics and the
function rectangle() (Question 11a) to draw a sequence of
rectangles of
specified size and orientation. Begin drawing each rectangle at the
initial

location of the passed turtle parameter. Rotate each rectangle
after the
first one counterclockwise by a specified angle. Make the second
(and
fourth) side of each rectangle twice the length of the first (and
third)
side.
The function panels() should repeatedly call rectangle() to draw
rectangles
of increasing size, rotated by a specified angle.
The function panels() takes 5 parameters:
i.
t, a turtle used for drawing
ii. initSize, the length of the short side of the first rectangle
iii. delta, the increase in length of the short side of successive
rectangles
iv. numPanels, the number of rectangles to draw
v.
angle, the number of degrees to rotate successive rectangles
If panels() is called by the following code, the graphic below
would be
correct output. (Hint: panels() should draw with the passed turtle,
whatever location and orientation the turtle is in.)
import turtle
s = turtle.Screen()
shelly = turtle.Turtle()
panels(shelly, 20, 15, 8, 20) Question 12
The letters a, e, i, o and u are the only vowels. Write a function
named
vowelUseDict() takes a string t as a parameter and computes and
returns a
dictionary with the number of words in t containing each vowel.
Assume that
the given text contains only lower case letters and white space.
Input:
Return: t, a string consisting of lower case letters and white space
a dictionary in which each vowel is a key and its value is

the number of words containing that vowel For example, the
following would be correct output.
text = 'like a vision she dances across the porch as the radio plays'
print(vowelUseDict(text))
{'e': 5, 'u': 0, 'o': 4, 'a': 6, 'i': 3}
Question 13
Write a function named longestWord() that find the length of the
longest
word in each line in a file and writes that length to a new file.
The function longestWord() takes two string parameters. The
first parameter
is the name of an input file that exists before longestWord() is
called.
The second parameter is the name of an output file that
longestWord()
creates and writes to.
Assume that the input file contains only letters and white space.
Assume
that the input file is in the current working directory and write
the
output file to that directory.
The function longestWord() should write a line to the output file
only if
the line in the input file is not empty, that is, it contains at least
one
word. For example, if the following is the content of the file
trouble.txt:
We surely got trouble
Right here in River City
Gotta figger out a way
To keep the young ones moral after school
The following function call:
inF = 'trouble.txt'
outF = 'troubleLongest.txt'
longestWord(inF, outF)
should create the file longestWord.txt with the content:

Question 11a (8 points)
Write a function named halfSquare that uses turtle graphics to draw
half of a square on the screen. This
involves drawing two lines of equal length, making a 90 degree turn
after each. For full credit, these
repeated operations should be performed in a loop.
The function halfSquare takes two parameters
i. t, a turtle that is used for drawing
ii. length, the length of the lines
The function halfSquare should begin drawing without changing the
position or orientation of the turtle t. The turtle t that is passed to

halfSquare may initially be either up or down and may be at any
location on the screen and in any orientation.
The figure at the right shows sample graphical output of halfSquare.
Question 11b (12 points)
Write a function named halfSquares that calls the function halfSquare
repeatedly to draw connected
half squares of increasing size. (You can use this technique to draw a
spiral pattern.)
The function halfSquares takes four parameters:
i.
ii.
iii.
iv. t, a turtle used for drawing
initial, the length of a side of the first half square
increment, the increase in side length of each successive half square
reps, the number of half squares to draw For example, the graphical
output of the code below should
look like the illustration at the right:
import turtle
s = turtle.Screen()
turt = turtle.Turtle()
halfSquares(turt, 20, 20, 10) Question 12 (20 points)
Write a function named wordCount that counts how many words
there are in each line of an input file
and writes that count to a corresponding line of an output file. The
input file already exists when
wordCount is called. wordCount creates the output file.
Input. The function wordCount takes two parameters:
i. inFile, a string that is the name of a text file that is to be read and
analyzed. The file that inFile
refers to contains only upper and lower case letters and white space
(no punctuation marks or
other special characters).
ii. outFile, a string that is the name of the file to which wordCount
writes its output.
The input file is in the current working directory and you should
create the output file to that directory.

Output. For each line of inFile, wordCount should write a
corresponding line to outFile containing a
single integer: the number of words on the line.
If the content of the file catInTheHat.txt is below,
The sun did not shine

Write a function named initialVowels that analyzes the contents of a
text file for words that begin with a
vowel. The letters a, e, i, o and u are vowels.
The function initialVowels should return a dictionary of vowel:word-
list pairs. Each vowel should be a
key in the dictionary if and only if it is the first letter of some word in
the input file. The value of a key
is a list of all the words in the input file in which that vowel is the first
letter. (Hint: your job is easier if
you lowercase the text in the input file.)
Input. The function initialVowels takes a single parameter:
i. inFile, a string that is the name of a text file. This file contains only
upper and lower case letters
and white space (no punctuation marks or other special characters). It

is in the current working
directory.
Output. Return a vowel:word-list dictionary
For example, if the file named catInTheHat.txt contains the same text
as in Question 12, then the
function call
print(initialVowels('catInTheHat.txt')) should output
{'i': ['it', 'in', 'i', 'i', 'i'], 'a': ['all', 'and']}

CS 100 sumOfCubes Challenge Problem 1
Write a function named sumOfCubes that takes a single integer
parameter, n, and returns the number of triplets of positive perfect
cubes whose sum is less than or equal to n.
For example, let n = 10. The triplets of positive perfect cubes whose
sum is less than or equal to 10 are
1, 1, 1
1, 1, 8
Therefore, sumOfCubes(10) = 2.
This problem also has a performance requirement: When n =
1,000,000 sumOfCubes must return the answer in less than one
minute.
sumOfCubes Challenge Problem 2.

We measure the efficiency (or conversely, the cost) of an algorithm
by the number of times that some key operation is performed. In this
case, the comparison between a sum of three cubes and the parameter
n is the likely measure.
Extend your solution to Problem 1 to count the number of

HEAR the sledges with the bells,
Silver bells!
What a world of merriment their melody foretells!
How they tinkle, tinkle, tinkle,
In the icy air of night!
While the stars, that oversprinkle
All the heavens, seem to twinkle
With a crystalline delight;
Keeping time, time, time,
In a sort of Runic rhyme,
To the tintinnabulation that so musically wells
From the bells, bells, bells, bells,

Bells, bells, bells—
From the jingling and the tinkling of the bells.
Hear the mellow wedding bells,
Golden bells!
What a world of happiness their harmony foretells!
Through the balmy air of night
How they ring out their delight!
From the molten-golden notes,
And all in tune,
What a liquid ditty floats
To the turtle-dove that listens, while she gloats
On the moon!
Oh, from out the sounding cells,
What a gush of euphony voluminously wells!
How it swells!
How it dwells
On the Future! how it tells
Of the rapture that impels
To the swinging and the ringing
Of the bells, bells, bells,

Of the bells, bells, bells, bells,
To the rhyming and the chiming of the bells!
Hear the loud alarum bells,
Brazen bells!
What a tale of terror, now, their turbulency tells!
In the startled ear of night
How they scream out their affright!
Too much horrified to speak,
They can only shriek, shriek,
Out of tune,
In a clamorous appealing to the mercy of the fire,
In a mad expostulation with the deaf and frantic fire,
Leaping higher, higher, higher,
With a desperate desire,
And a resolute endeavor
Now—now to sit or never,
By the side of the pale-faced moon.
Oh, the bells, bells, bells!
What a tale their terror tells

Of Despair!
How they clang, and clash, and roar!
What a horror they outpour
On the bosom of the palpitating air!
Yet the ear it fully knows,
By the twanging
And the clanging,
How the danger ebbs and flows;
Yet the ear distinctly tells,
In the jangling
And the wrangling,
How the danger sinks and swells,—
By the sinking or the swelling in the anger of the bells,
Of the bells,
In the clamor and the clangor of the bells!
Hear the tolling of the bells,
Iron bells!

What a world of solemn thought their monody compels!
In the silence of the night
How we shiver with affright
At the melancholy menace of their tone!
For every sound that floats
From the rust within their throats
Is a groan.
And the people—ah, the people,
They that dwell up in the steeple,
All alone,
And who tolling, tolling, tolling,
In that muffled monotone,
Feela glory in so rolling
On the human heart a stone—
They are neither man nor woman,
They are neither brute nor human,
They are Ghouls:
And their king it is who tolls;
And he rolls, rolls, rolls,
Rolls
A pæan from the bells;

And his merry bosom swells
With the pæan of the bells,
And he dances, and he yells:
To the pæan of the bells,
Of the bells:
To the throbbing of the bells,
Of the bells, bells, bells—
To the sobbing of the bells;
As he knells, knells, knells,
In a happy Runic rhyme,
To the rolling of the bells,
Of the bells, bells, bells:
To the tolling of the bells,
To the moaning and the groaning of the bells.

Arise to birth with me, my brother.
Give me your hand out of the depths
sown by your sorrows.
You will not return from these stone fastnesses.
You will not emerge from subterranean time.
Your rasping voice will not come back,
nor your pierced eyes rise from their sockets.
Look at me from the depths of the earth,
tiller of fields, weaver, reticent shepherd,
groom of totemic guanacos,
mason high on your treacherous scaffolding,
iceman of Andean tears,
jeweler with crushed fingers,
farmer anxious among his seedlings,

potter wasted among his clays--
bring to the cup of this new life
your ancient buried sorrows.
Show me your blood and your furrow;
say to me: here I was scourged
because a gem was dull or because the earth
failed to give up in time its tithe of corn or stone.
Point out to me the rock on which you stumbled,
the wood they used to crucify your body.
Strike the old flints
to kindle ancient lamps, light up the whips
glued to your wounds throughout the centuries
and light the axes gleaming with your blood.
I come to speak for your dead mouths.
Throughout the earth
let dead lips congregate,
out of the depths spin this long night to me
as if I rode at anchor here with you.

And tell me everything, tell chain by chain,
and link by link, and step by step;
sharpen the knives you kept hidden away,
thrust them into my breast, into my hands,
like a torrent of sunbursts,
an Amazon of buried jaguars,
and leave me cry: hours, days and years,
blind ages, stellar centuries.
And give me silence, give me water, hope.
Give me the struggle, the iron, the volcanoes.
Let bodies cling like magnets to my body.
Come quickly to my veins and to my mouth.
Speak through my speech, and through my blood.

CSC 110 Assignment 6 -- Voter Participation Data

Instructions: For this assignment, you will write a program
that reads voter participation data from a file and processes that
data in several different ways, including writing a report to a
different file.
Data File Format
1952
1533500
1392594
1116414
1956
1622500
1451375
1164104
...
The voter participation data we will work with is stored in a
simple text file. Each line of the file contains one of 4 different
things:
 a year
 the estimated number of eligible voters for that year
 the number of registered voters for that year
 the number of ballots cast for that year
The file format is highly structured. Years are listed in
order. On the line after each year is the estimated number of
eligible voters for that year. On the next line is the number of

registered voters for that year. On the next line is the number of
ballots cast for that year. This sequence is repeated for each
year. The first two years of data from one of the sample files are
shown at right to illustrate this. Here are links to two sample
files: PresidentialElections.txt MidTermElections.txt [Data
source: http://www.sos.wa.gov/elections/voter_participation.aspx
(Links to an external site.)]
Program Specification
Write a program that does the following:
 Allow the user to specify the name of an input file containing
voter participation data (that way, different data files can be
tested).
 Read the data from the file and write a report out to a new
file as follows:
 The name of the output file should be the name of the
input file preceded with the word 'REPORT-'. So, if
the input file is named 'PresidentialElections.txt', then
the output file should be named 'REPORT-
PresidentialElections.txt', but if the input file is named
'MidTermElections.txt', then the output file should be
named 'REPORT-MidTermElections.txt', etc. Your
program should work with any properly formatted
data file -- not just the two listed here.
 The report should include one line for each year in the
data file. The line should show a sentence containing
the year, the percentage of eligible voters who
registered, and the percentage of eligible voters who
cast ballots (voted). The percentages should be
rounded to two places after the decimal point. Here is
an example of what the first part of the output file
would look like for the data shown above:

In 1952, 90.81% registered and 72.80% voted.
In 1956, 89.45% registered and 71.75% voted.
...
 Finally, show the following information in the Python shell
window in a nicely-formatted, easy to understand report:
 the total number of years listed
 the total number of ballots cast in all those years
 the average percentage of eligible voters who registered
 thenumberof years with less than 60% of registered
voters casting ballots
 thepercentageof years with more than 80% of
registered voters casting ballots
 A sentence showing the name of the report file
Here is an example of what the report would look like for the first
file:
The total number of years listed: 17
Total ballots cast in all these years: 34,436,792
Average percentage of eligible voters registered: 79.55%
Number of years with less than 60% of registered voters casting ballots: 0
Percentage of years with more than 80% of registered voters casting ballots:
47.1%
An output file named REPORT-PresidentialElections.txt has been created.
Development Tips:
1. Use a loop to read the data from the file and process the
data. Only one loop is needed to do everything!
2. Use acounterto count the total number of years.

3. Usecountersalong with 'if' statements inside the loop to
count the number of years with less than 60% or more than
80% of registered voters casting ballots.
4. Use anaccumulatorto add up the number of ballots
cast. You will also need one more accumulator.
5. Remember that counters and accumulators always need to
beinitializedbefore the beginning of the loop.
6. Plan your program carefully on paper before you start
writing code. Remember that you need to "process" the
fileone record at a time. You can't "jump around" to get
the info you need like you can do as a human reader. "Be
the computer!"
The easiest solution involves a loop that repeats one time for
each YEAR. Hint: if you have a line in the file with a year,
the file format guarantees that it will be followed by three
more lines containing the information for that year. As a
result, you can safely read those values into the program
right in the body of the loop.
Testing -- Be sure to carefully test your program with different
files. You can create a simple, short file to make testing easy. As
always, be sure to document your testing in comments at the end
of the program. Your comments should also say if you think any
part of the assignment requirements have not been met.
Grading
/10 correctly determines 5 quantities to be shown in the shell
window: # years, # ballots counted, average percentage of eligible
voters who registered, <60% years and >80% years
/12 reads and writes files properly (reads data, writes out a report
file, closes files, no errors)
/3 documented test cases
/5 proper comments; good variable names; declarations;
indenting; blank lines

CSC 110 This program use Python 3 Objective
This program use Python 3
Objective:
 Practice working with a list of numbers.
 Practice writingfunction definitionsthat
useparametersandreturna value.
 Practice using astring accumulator.
Instructions:
Your employer needs a program that analyzes the monthly sales
figures for each division.
Write a Python program that allows the user to enter a series of
numbers and places the numbers (not string values) in
a list. Each number entered by the user is the monthly sales
amount for one division. Use a sentinel-controlled loop to get
input from the user and place each value entered into the list as
long as the value is not negative. As soon as any negative value is
entered, stop the loop (without putting that illegal value into the
list).
One objective of this assignment is to apply algorithms we have
studied to solve problems. You will do this by writing a function
definitionto implement each algorithm. Every function must get
information only from its parameters, not from "global"
variables. Several of these tasks can also be accomplished with

built-in functions. In those cases, your code should demonstrate
both approaches and show that the results are the same.
Add code to your program to do the following:
1. Write a function definition that uses a loopand astring
accumulatorto produce andreturn astringresultthat
includes the user-entered sales figures formatted to look
similar to this when it is printed:
{$12.95, $1,234.56, $100.00, $20.50}
Notice the dollar signs, commas, digits after the decimal
point, and curly braces. Plan this one on paper before you
start writing code. Add code that calls this function and
prints the result.
2. Show thehighestnumber in the list -- the sales leader! Do this
in two ways. First, use the built-in 'max' function. Then,
write your own 'max2' function definition that accomplishes
the same thing by using a loop to find the highest value.
3. Show thelowestnumber in the list -- the sales loser. Do this in
two ways. First, use the built-in 'min' function. Then, write
your own 'min2' function definition that accomplishes the
same thing by using a loop to find the lowest value.
4. Show the total sales for the company for the month --
thesumof all the numbers in the list. Once again, write a
function definition that uses a loop and an accumulator to
compute this sum.
5. Show theaverageof all the numbers in the list. (Be sure to
carefully check the result!)
6. Ask the user to enter athreshold(a number). Write a
function that takes a list and the threshold as parameters,
and returns a new list that contains all values in the original
list that aregreaterthan or equal to the threshold-- these
divisions get awards for high sales! The new list may, of
course, be empty.
Program Organization:
The program should be organized as a series of function

definitions. The 'main' function should contain the user interface
as well as code that "calls" the other functions and then shows the
results to the user. Only the 'main' function should interact with
the user. No other function should print anything; rather, each
function "returns" a value. Do not use any global variables.
Testing:
As always, be sure to test each result using representative data to
make sure it is correct, and include comments showing
documented test cases in your program.

In Programming Exercise 1 in Chapter 1
20. C. d. In Programming Exercise 1 in Chapter 1, we defined a class
roman'rype to implement Roman numerals in a program. In that
exercise, we also implemented a fianction, roman'I'oDecimal, to
con—
vert a Roman numeral into its equivalent decimal number. Modify the
definition of the class roman'rype so that the data mem—
bers are declared as protected. Use the class string to manipulate
the strings- Furthermore, overload the stream insertion and stream
extraction operators for easy input and output. The stream insertion
operator outputs the Roman numeral in the Roman format. Also,
include a member fianction, decimalToRoman, that converts the
decimal number (the decimal number must be a positive integer) to an
equivalent Roman numeral format- Write the definition of the
member
fimction decimalToRoman. For simplicity, we aSSume that only the

letter I can appear in front of
another letter and that it appears only in ernt of the letters V and x.
For
example, 4 is represented as IV, 9 is represented as IX, 39 is
represented
as XXXIX, and 49 is represemed as XXXXIX. Also, 40 will be
represented
as moot, 19E!I will be represented as cm, and so on. Derive a class
extRomanType from the class romanType to do the
following. In the class extRomanType, overload the arithmetic
operators +, -, * , and / so that arithmetic operations can be performed
on Roman numerals- Also, overload the pre— and postincrement and
decrement operators as member fianctions of the class
extRomanType. To add (subtract, multiply, or divide) Roman
numerals, add (subtract,
multiply, or divide, respectively) their decimal representations and
then
convert the reSult to the Roman numeral format. For subtraction, if
the
first number is smaller than the sec0nd number, output a message
saying
that, “Because the first number is smaller than the second,
the numbers cannot be subtracted”. Similarly, for division, the
numerator must be larger than the denominator. Use similar conven—
tions for the increment and decrement operators. Write the definitions
of the fianctions to overload the operators
descnbed in part b. Write a program to test your class extRoman'rype.

Quiz Write a method that computes the average

Question 1 (10 points)
Write a method that computes the average of the values in an
array of doubles.
The header of the method is as follows:
public static double average(double[] x)
Write a complete Java class that will create a 2D array of
randomly generated ints with dimensions of 5 rows and 10
columns. Print the values of each cell to a 5x10 table.
(Note: a complete Java class means the code should compile and
run without issue. Be sure the output displays a set of random ints
formatted in 5 rows by 10 columns.
You have an int array named examScores that is 1000 elements in
length.
Provide a single line of code that would sort the examScores.
(Note: You do not need to provide the import statements
supporting the line of code)
