2 public class Test2 {
3 public static void main(String[] args) {
4 ArrayList<Integer> numbers = new ArrayList<Integer>();
5 for (int i = 1; i <= 3; i++) {
6 for (int j = 1; j <= 3; j++) {
7 int value = i * 2 / 2;
8 {Integer intObj = new Integer(value); numbers.add(intObj);}
} }
9 { System.out.println(numbers); }
}}
What will be result when compiled and run?
(A) [1, 2, 3, 1, 2, 3, 1, 2, 3]
(B) [1, 1, 1, 2, 2, 2, 3, 3, 3]
