STEP 1: Largest (10 points)
Write a Java application program called Largest.java that inputs a series of 10 single-digit numbers
and determines and prints the largest of the numbers. Except main() method, no other user-defined
method is required. Your program should use at least the following three variables
1. counter: A counter to count to 10 (that is, to keep track of how many numbers have been
input and to determine when all 10 numbers have been processed);
2. number: The current digit input to the program; and
3. largest: The largest number found so far.
When each number is entered, make sure it is a single digit number, that is 0 to 9.

STEP 2: Palindrome (15 points)
A palindrome is a sequence of characters that reads the same backward as forward. For example,
each of the following five-digit integers is a palindrome: 12321, 55555, 45554, and 11611. Write an
application called Palindrome.java that asks the user to enter in a five-digit integer and
determines whether it is a palindrome. If the number is not five digits long, display an error

2. message dialog indicating the problem to the user. When the user dismisses the error dialog, allow
the user to enter a new value.
Your program will have the following four methods
1. main() method, which controls the execution of the program;
2. retrieveInput() method, which prompts and retrieves the input values;
3. check() method, which determines whether it is a palindrome; and
4. display() method, which displays the result.

STEP 3: Diamond (15 points)

3. Write a program called Diamond.java that uses a method diamondOfAsterisks() that displays a
diamond (the row number of a diamond must be odd) of asterisks whose row is specified in an
integer parameter row. For example, if the user enters a 7, then the diamond will have seven rows
and the method will display the pattern of asterisks. Below is an example of the diamond displayed
when 7 is entered.
