装饰模式——java实现

问题描述：

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。

Java源代码：

//Phone.java
package shiyan11;

public interface  Phone {
        public void call();
} 
//SimplePhone.java
package shiyan11;

public class SimplePhone implements Phone{
    public SimplePhone(){
        System.out.println("手机收到来电");
    }
    public void call(){
        System.out.println("发出声音：主人来电话啦！");
    }
} 
//UpgradePhone.java
package shiyan11;

public class UpgradePhone implements Phone{
    private Phone phone;
    public UpgradePhone(Phone a){
        phone=a;
    }
    public void call(){
        phone.call();
    }
} 
//JarPhone.java
package shiyan11;

public class JarPhone extends UpgradePhone{
    public JarPhone(Phone phone){
        super(phone);
        System.out.println("***增加振动的功能***");
    }
    public void shoke(){
        System.out.println("振动：嗡嗡嗡");
    }
} 
//ComplexPhone.java
package shiyan11;
public class ComplexPhone extends UpgradePhone{
    public ComplexPhone(Phone phone){
        super(phone);
        System.out.println("***增加闪光功能***");
    }
    public void light(){
        System.out.println("灯光闪烁：咔嚓");
    }
}
