设计模式总结6--适配器模式 adapter pattern

适配器模式将一个类的接口，转化成客户期望的另一个接口，适配
器让原本接口不兼容的类可以合作无间

public interface Sheep{
    public void run();
    public void ho();
}

public class Wolf{
    public void run(){
        System.out.println("狼跑");
    }
    public void ho(){
        System.out.println("狼嚎");
    }
}

public class SheepAdapter implements Sheep{
    private Wolf wolf;
    public SheepAdapter(Wolf wolf){
    this.wolf = wolf;
    }
    @Override
    public void run(){
        wolf.run();
    }
    @Override
    public void ho(){
        wolf.ho();
    }
}

测试适配器

public static void main(String[] args){
    //狼
    Wolf wolf = new Wolf();
    //披着羊皮的狼
    Sheep sheep = new  SheepAdapter(wolf);
    sheep.run();
    sheep.ho();
}
