关于BINDING的一个考试题，有兴趣可以试试
要期末考试了，今天在家复习。这是我期中考试的一道题，关于BINDING的。有兴趣的朋友可以试试。过几天我发答案上来。
程序代码：public class GrandParent{
public GrandParent(){}
public double giveMoney(Parent p){
if(p instanceof Child){
amount = 15.5;
else
amount = 515.5;
return amount;
}
public class Parent extends GrandParent{
public Parent(){}
public int takePicture(Object o){
return 314;
}
public int takePicture(Parent p){
return 414;
}
}
public class Child extends Parent{
public int takePicture(Parent p){
return 514;
}
public int takePicture(Child c){
return 614;
}
}有如下：
Child child1 = new Child(); Parent parent1 = new Parent(); Parent parent2 = new Child(); Grandparent grandpa = new Parent();
问题：
1 System.out.println(child1.takePicture(grandpa)); 2 System.out.println(grandpa.giveMoney(parent2)); 3 System.out.println(grandpa.takePicture(child1)); 4 System.out.println(parent2.takePicture(child1));
