Analyze the following code: public class Test { public static void main(String[] args) { int[] a = new int [4] ; a [1] = 1; } = new int [2] ; System.out.println("a[1] 13 " + a[1]); The program displays a[1] is 0 D O The program displays a[1] is 1. O The program has a compile error because new int[2] is assigned to a O The program has a runtime error because a[1] is not initialized
