设计模式（七）--适配器模式

适配器模式：将一个类的接口，转换成客户期望的另外一个接口，适配器将原本接口不兼容的类可以合作无间。

意图：不改变接口，但加入责任 

/**
 *暴露的公共接口
 * Created by Administrator on 2018/1/9.
 */
public interface Duck {
    void quack();
    void fly();
}

/**
 * 需要被适配的接口
 * Created by Administrator on 2018/1/9.
 */
public interface Turkey {
    void gobble();
    void fly();
}

/**
 * Created by Administrator on 2018/1/9.
 */
public class WildTurkey implements  Turkey {
    @Override
    public void gobble() {
        System.out.println("wildturkey is gobble");
    }

    @Override
    public void fly() {
        System.out.println("wildturkey is fly");
    }
}

/**
 * 适配器
 * Created by Administrator on 2018/1/9.
 */
public class TurkeyAdapter implements Duck {

    private Turkey turkey;

    public TurkeyAdapter(Turkey turkey) {
        this.turkey = turkey;
    }

    @Override
    public void quack() {
        turkey.gobble(); //这里进行适配
    }

    @Override
    public void fly() {
        turkey.fly();
    }
}

/**
 * Created by Administrator on 2018/1/9.
 */
public class TestAdapter {
    public static void main(String[] args) {
        Turkey wildTurkey = new WildTurkey();
        wildTurkey.gobble();

        /**
         * 这里进行适配
         * **/
        TurkeyAdapter turkeyAdapter = new TurkeyAdapter(wildTurkey);
        turkeyAdapter.quack();
        turkeyAdapter.fly();
    }
}
