What will be the output?public class Test{ public static void main(String[] args){ int[] a = new int[4]; a[1] = 1; a = new int[2]; System.out.println("a[1] is " + a[1]); }}
A). The program has a compile error because new int[2<sp< label=""></sp<>
B). The program has a runtime error because a[1
C). a[1] is 0
D). a[1] is 1
Analyze the following code and choose the correct answer.int[] arr = new int[5];arr = new int[6];
A). The code has compile errors because the variable arr cannot be changed once it is assigned.
B). The code has runtime errors because the variable arr cannot be changed once it is assigned.
C). The code can compile and run fine. The second line assigns a new array to arr.
D). The code has compile errors because we cannot assign a different size array to arr.
Determine output:public class Test{ public static void main(String[] args){ int[] x = {1, 2, 3, 4}; int[] y = x; x = new int[2]; for(int i = 0; i < x.length; i++) System.out.print(y[i] + " "); }}
A). 1 2 3 4
B). 0 0 0 0
C). 1 2
D). 0 0
E). None of these
What is output of the following code:public class Test{ public static void main(String[] args){ int[] x = {120, 200, 016 }; for(int i = 0; i < x.length; i++) System.out.print(x[i] + " "); }}
A). 120 200 16
B). 120 200 14
C). 120 200 016
D). 016 is a compile error. It should be written as 16.
