Object Reference

在 java 中所有的物件皆用 Reference 表示,
如 assign A 給 B, 則 A 和 B 指向相同區塊.

{{{
import andy.Point;

public class ObjectReference {

public static void main(String[] args) {
Point p1 = new Point();
Point p2 = p1;

Object ob1 = p1;
System.out.println("p1: " + p1 + ", p2: " + p2 + ", Object p1" + ob1);

}

}


}}}

{{{
