10. What will be the output of the following Java Program?

class Test {
    public static void main(String args[]) {
        int arr[2];
        System.out.println(arr[0]);
         System.out.println(arr[1]);
   }
}

12. What will the following print ? public class Test public static void main (String[] args) boolean bl = true; boolean b2 = false; boolean b3 = true; if ((bl && b2) || (b2 && b3) || b2) System.out.print("ok"); if ((bl && b2) || (b2 && b3) 11 (bl || b2)) System.out.println("dokey"); (A) No output is produced (B) ok (C) dokey (D) Compile-time error (E) ok dokey

3. What is printed to the screen when the following program is run? (6 points) public class Alias Test { public static void main(String[] args) { int) foo = {1,2,3,4,5}; int[] bar = {20, 21, 22, 23); int) chocolate = bar; bar[0] = 30; chocolate [1] = chocolate [0] + foo(0); System.out.println("Phase 1"); System.out.println (bar[0]); System.out.println (chocolate[0]); System.out.println (foo [0]); System.out.println (bar[1]); bar - foo; foo - chocolate; foo [31 - foo [2] + foo[1]; System.out.println("Phase 2"); System.out.println (foo [1]); System.out.println (foo [2]); System.out.println (foo [3]); foo = new int [10); foo [0] = 3; System.out.println("Phase 3"); System.out.println(chocolate[0]); System.out.println (chocolate[1]); System.out.println(chocolate[21); System.out.println(chocolate[3]); //WHAT IS PRINTED TO THE SCREEN IN THIS RUN? What is printed to the screen when the above program is run?
