11.6实验11：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；

package test11;

 

public abstract class Phone {

    public void serviceCall() {

 

    }

}

 

 

package test11;

 

 

public class ComplexPhone extends PhoneDecoration {

    public ComplexPhone(Phone phone) {

        super(phone);

    }

 

    @Override

    public void serviceCall() {

        super.serviceCall();

        System.out.println("ComplexPhone：发出声音、震动并灯光闪烁提醒主人电话来了");

    }

}

 

package test11;

 

public class PhoneDecoration extends Phone {

    private Phone phone = null;

 

    public PhoneDecoration(Phone phone) {

        if (phone != null) {

            this.phone = phone;

        } else {

            this.phone = new SimplePhone();

        }

    }

 

    @Override

    public void serviceCall() {

        phone.serviceCall();

    }

}

 

package test11;

 

public class Client {

 

    public static void main(String[] args) {

 

        Phone p1 = new SimplePhone();

        System.out.println("生产简单手机");

        p1.serviceCall();

 

        System.out.println("***********************");

        Phone p2 = new JarPhone(p1);

        System.out.println("升级为JarPhone手机");

        p2.serviceCall();

        System.out.println("***********************");

 

        Phone p3 = new ComplexPhone(p2);

        System.out.println("升级为ComplexPhone手机");

        p3.serviceCall();

    }

}

 

package test11;

 

public class JarPhone extends PhoneDecoration {

    public JarPhone(Phone phone) {

        super(phone);

    }

 

    @Override

    public void serviceCall() {

        super.serviceCall();

        System.out.println("JarPhone：发出声音并震动提醒主人电话来了");

    }

}

 

package test11;

 

public class SimplePhone extends Phone {

 

    public void serviceCall() {

        System.out.println("SimplePhone：发出声音提醒主人电话来了");

    }

}

3.注意编程规范。
