每日随笔——装饰模式

[实验任务一]：手机功能的升级

用装饰模式模拟手机功能的升级过程：简单的手机(SimplePhone)在接收来电时，会发出声音提醒主人；而JarPhone除了声音还能振动；更高级的手机(ComplexPhone)除了声音、振动外，还有灯光闪烁提示。

实验要求：

1.提交类图；

2.提交源代码；

3.注意编程规范。

 

源码：

Client
package sc11;

public class Client {

    public static void main(String[]args) {
        Phone p=new SimplePhone();
        p.receiveCall();
        System.out.println("Simple");
        Phone p1=new JarPhone(p);
        p1.receiveCall();
        System.out.println("JarPhone");
        Phone p2=new ComplexPhone(p1);
        p2.receiveCall();
        System.out.println("ComplexPhone");
    }

}

ComplexPhone
package sc11;

public class ComplexPhone extends PhoneDecorator{

    public ComplexPhone(Phone p) {
        // TODO Auto-generated constructor stub
        super(p);
    }
    public void receiveCall() {
        super.receiveCall();
        System.out.println("接受来电,灯光闪烁");
    }

}

JarPhone

    public JarPhone(Phone p) {
        // TODO Auto-generated constructor stub
        super(p);
    }
    public void receiveCall() {
        super.receiveCall();
        System.out.println("接受来电,手机震动");
    }

}

            phone=p;
        }else {
            phone=new SimplePhone();
        }
    }
    @Override
    public void receiveCall() {
        // TODO Auto-generated method stub
        phone.receiveCall();
    }

}

SimplePhone
package sc11;

public class SimplePhone extends Phone {

    @Override
    public void receiveCall() {
        // TODO Auto-generated method stub
        System.out.println("接受来电,电话响了");
    }
