以下代码输出结果为：class intWrap { int x;} public class Main { public static void main(String[] args) { intWrap i = new intWrap(); i.x = 10; intWrap j = new intWrap(); j.x = 20; swap(i, j); System.out.println("i.x = " + i.x + ", j.x = " + j.x); } public static void swap(intWrap i, intWrap j) { int temp = i.x; i.x = j.x; j.x = temp; }}

（A）i.x = 20, j.x = 10

（B）i.x = 10, j.x = 20

（C）i.x = 10, j.x = 10

（D）i.x = 20, j.x = 20
