JAVA Array Analyze the following code and choose the correct answer.int[] arr = new int[5];arr = new int[6]; The code has compile errors because the variable arr cannot be changed once it is assigned. The code has runtime errors because the variable arr cannot be changed once it is assigned. The code can compile and run fine. The second line assigns a new array to arr. The code has compile errors because we cannot assign a different size array to arr. The code has compile errors because the variable arr cannot be changed once it is assigned.

JAVA Array What will be the output?public class Test{ public static void main(String[] args){ int[] x = new int[3]; System.out.println("x[0] is " + x[0]); }} The program has a runtime error because the array elements are not initialized. The program has a compile error because the size of the array wasn't specified when declaring the array. The program runs fine and displays x[0] is 0. The program has a runtime error because the array element x[0] is not defined. The program has a runtime error because the array elements are not initialized.
