大橙子网站建设,新征程启航
为企业提供网站建设、域名注册、服务器等服务
客户端获得自定义对象包路径必须和服务器端相同,当然在客户端也可以不用建该对象,可以将客户端的自定义对象打成jar包,然后在客户端引用。

猜想用反射也可以实现改对象,但目前没有写相关例子。
pimport java.io.Serializable;/pppublic class Hello implements Serializable {
/**
*客户端必须有与服务器端相同的自定义对象
*/

private String id;
private String name;
public String getId() {

public void setId(String id) {
this.id = id;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;

1.implements PCI是实现PCI 接口的意思;
2.不是;这两个方法是必须写的,不能少;这两个方法来自接口中的,既然现实了PCI接口,就一定要实现接口中的所有方法
3.PCI nc= new NetworkCard(); 因为NetworkCard实现了PCI接口,PCI就类似是NetworkCard的父类,这个体现了面相对象编程中的多态;就好比你是一个男生,我可以说你是一个人吧,意思是一样的;
4.PCI nc = new PCI()这个是不能直接这样写的,因为PCI是接口,接口中没有构造方法,这个是new不出来对象的

三个错:
1.Chicken 类里的howtoeat方法改howtoEat;
2.Apple类和Orange 放到Fruit 类外面。
3。Chicken 类的构造方法需要给重量参数,因为你只定义了一个构造方法。
我调试的没问题,改后代码:
interface Edible{
public String howtoEat();
}
class Animal{
}
class Chicken extends Animal implements Edible,Comparable{
int weight;
public Chicken(int weight){
this.weight=weight;
}
public String howtoEat(){
return "fry it";
}
public int compareTo(Object o){
return weight-((Chicken)o).weight;
}
}
class Tiger extends Animal{
}
abstract class Fruit implements Edible
{}
class Apple extends Fruit {
public String howtoEat(){
return "Make apple cider";
}
class Orange extends Fruit{
public String howtoEat(){
return "Make orange juice";
}
}
}
public class Test{
public static void main(String[] args){
Object[] objects={new Tiger(),new Chicken(10),new Apple()};
for(int i=0;iobjects.length;i++){
showObject(objects[i]);
}
}
public static void showObject(Object object){
if(object instanceof Edible)
System.out.println(((Edible)object).howtoEat());
}
}
