装饰模式javac++

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。

        JarPhone p1=new JarPhone(p);
        p1.shoke();
        System.out.println("JarPhone");
        ComplexPhone p2=new ComplexPhone(p1);
        p2.light();
        System.out.println("ComplexPhone");
