复习：GoF的23种设计模式之Template Method模式（行为型）

public class TemplateMethodTest {
    public static void main(String[] args) {
        //普通用户请求时
        MotherAbstractClass common = new CommonConcreteClass();
        common.response();
        //vip用户请求时
        MotherAbstractClass vip = new VipConcreteClass();
        vip.response();
    }
}

abstract class MotherAbstractClass {
    public final void response() {
        open();
        data();
    }
    public abstract void open();
    public abstract void data();
}

class VipConcreteClass extends MotherAbstractClass {
    @Override
    public void open() {
        System.out.println("我是vip");
    }
    @Override
    public void data() {
        System.out.println("我是vip的响应数据");
    }
}

    }
    @Override
