1. Please only answer if you are completely sure of your answer: You will notice that some
choices have been eliminated already. That is because I have been able to verify these are
incorrect. Please answer both questions.
1.
Consider the following code snippet:
int[][] arr = { { 13, 23, 33 }, { 14, 24, 34 } };
Identify the appropriate statement to display the value 24 from the given array?
Select one:
a. System.out.println(arr[1][2]);
c. System.out.println(arr[1][1]);
2.
Consider the following code snippet:
Identify the appropriate statement to display the value 24 from the given array?
Select one:
a. System.out.println(arr[1][2]);
b. System.out.println(arr[2][2]);
Solution
Please follow the data :
1)

2. For the given array int[][] arr = { { 13, 23, 33 }, { 14, 24, 34 } }; the values of the indexes
changes comparitively. So the 24 relies in the 1st column and the 1st row.
So the answer is OPTION C (System.out.println(arr[1][1])) = 24
2)
For the given array int[][] arr =
{
{ 13, 23, 33 },
{ 14, 24, 34 }
};
the indexing starts as usual for a normal matrix, so the 24 value relies on the 1st column and 1st
row of the matrix , but the option is not provided in the choices, guess that might be eliminated.
So please check the option to get the value 24 from the matrix is :
(System.out.println(arr[1][1]))
But for the given option the output will be like :
a) (System.out.println(arr[1][2])) = 34
b) (System.out.println(arr[2][2])) = Exception in thread "main"
java.lang.ArrayIndexOutOfBoundsException: 2
at others.NewClass.main(NewClass.java:24)
Java Result: 1
The second option raises an exception as the array value that has been initialised is less than the
values queried by the output.
Hope this is helpful.
