What is the result of the program? public class B { public static void main(String[] args) { big_loop: for (int i = 0; i < 3 ; i++) { try { for (int j = 0; j < 3 ; j++) { if (i == j) continue; else if (i > j) continue big_loop; System.out.print("A"); } } finally { System.out.print("B"); } System.out.print("C"); } } }

java

What happens when you compile and run the following code? public class Test { static int[] arrInstance = new int[100]; public static void main(String[] args) { byte[] arrLocal = new byte[100]; for (int i = 0; i < 100; i++) if (arrInstance[i] != arrLocal[i]) { throw new IllegalStateException("error"); } } }
