本文介绍了一个使用Java实现的代理模式示例，展示了如何通过代理类间接地调用目标对象的方法，代理类实现了与目标对象相同的接口，从而可以控制对目标对象的访问。

package DesignPattern.ProxyPattern;

public interface IGiveGift {

    void GiveDolls();
    void GiveFlowers();
    void GiveChocolate();
}

package DesignPattern.ProxyPattern;

public class SchoolGirl {

    private String name;

    public SchoolGirl(String name){
        this.setName(name);
    }

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

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

package DesignPattern.ProxyPattern;

public class Pursuit implements IGiveGift {

    SchoolGirl mm;

    public Pursuit(SchoolGirl mm){
        this.mm=mm;
    }

    @Override
    public void GiveChocolate() {
        System.out.println(mm.getName()+" 送你洋娃娃");
    }

    @Override
    public void GiveDolls() {
        System.out.println(mm.getName()+" 送你鲜花");
    }

    @Override
    public void GiveFlowers() {
        System.out.println(mm.getName()+" 送你花");
    }
}

package DesignPattern.ProxyPattern;

public class Proxy implements IGiveGift{

    Pursuit gg;
    public Proxy(SchoolGirl mm){
        this.gg=new Pursuit(mm);
    }

    public void GiveDolls(){
        gg.GiveDolls();
    }

    public void GiveFlowers(){
        gg.GiveFlowers();
    }

    public void GiveChocolate(){
        gg.GiveChocolate();
    }
}

package DesignPattern.ProxyPattern;

public class Client {

    public static void main(String[] args)
    {
        SchoolGirl mm=new SchoolGirl("jiaojiao");
        Proxy daili=new Proxy(mm);
        daili.GiveDolls();
        daili.GiveFlowers();
        daili.GiveChocolate();
    }
}
