设计模式（一）之适配器模式

被适配的类：

public class Adaptee {
    public void specificMethod(){
        System.out.println("三脚插头");
    }
}

适配接口

public interface AppleInterface {
    public void phoneInterface();
}

适配器

public class Adapter implements AppleInterface {

    private Adaptee adaptee;

    public Adapter(Adaptee adaptee) {
        this.adaptee = adaptee;
    }

    @Override
    public void phoneInterface() {
        adaptee.specificMethod();
    }
}

参照类

public class Linghtning implements AppleInterface {
    @Override
    public void phoneInterface() {
        System.out.println("Linghtning.");
    }
}

调用者

public class Consumer {

    public static void main(String[] args) {
        // 适配到三脚插头
        AppleInterface linghtning = new Adapter(new Adaptee());
        linghtning.phoneInterface();

        // 只是自己
        linghtning = new Linghtning();
        linghtning.phoneInterface();
    }
}
