实验11：装饰模式

本次实验属于模仿型实验，通过本次实验学生将掌握以下内容： 

1、理解装饰模式的动机，掌握该模式的结构；

2、能够利用装饰模式解决实际问题。

 

[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。

 

 

 

public class JarPhone extends PhoneDecorator{

 

    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");

    }

 

}

 

public class PhoneDecorator extends Phone{

 

    private Phone phone;

    public PhoneDecorator(Phone p) {

        // TODO Auto-generated constructor stub

      if(p!=null) {

          phone=p;

      }else {

          phone=new SimplePhone();

      }

    }

    @Override

    public void receiveCall() {

        // TODO Auto-generated method stub

        phone.receiveCall();

    }

 

}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");        

    }

 

}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");
