实验11：装饰模式

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。

1. 提交类图；

2.提交源代码；

Phone.java

// 定义手机接口
interface Phone {
    String receiveCall();
}

SimplePhone.java

// 实现基础的SimplePhone类
class SimplePhone implements Phone {
    @Override
    public String receiveCall() {
        return "SimplePhone: 发出声音提醒主人";
    }
}

JarPhone.java

// 实现具有振动功能的JarPhone类
class JarPhone implements Phone {
    @Override
    public String receiveCall() {
        return "JarPhone: 发出声音提醒主人, 并振动";
    }
}

ComplexPhone.java

// 实现具有振动和灯光闪烁功能的ComplexPhone类
class ComplexPhone implements Phone {
    @Override
    public String receiveCall() {
        return "ComplexPhone: 发出声音提醒主人, 并振动, 并灯光闪烁提示";
    }
}

Main.java

public class Main {
    public static void main(String[] args) {
        // 创建不同手机类型的实例
        Phone simplePhone = new SimplePhone();
        Phone jarPhone = new JarPhone();
        Phone complexPhone = new ComplexPhone();

        // 模拟接收来电
        System.out.println("生产简单手机");
        System.out.println(simplePhone.receiveCall());
        System.out.println("---------------------");
        System.out.println("升级手机为JarPhone");
        System.out.println(simplePhone.receiveCall());
        System.out.println(jarPhone.receiveCall());
        System.out.println("---------------------");
        System.out.println("升级手机为ComplexPhone");
        System.out.println(simplePhone.receiveCall());
        System.out.println(jarPhone.receiveCall());
        System.out.println(complexPhone.receiveCall());
    }
}
