軟體設計模式————（裝飾模式）

[實驗任務一]：手機功能的升級

用裝飾模式模擬手機功能的升級過程：簡單的手機(SimplePhone)在接收來電時，會發出聲音提醒主人；而JarPhone除了聲音還能振動；更高階的手機(ComplexPhone)除了聲音、振動外，還有燈光閃爍提示。

實驗要求：

1.提交類圖；

2.提交原始碼；

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：發出聲音、震動並燈光閃爍提醒主人電話來了");
    }
}
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("生產簡單手機");
        p1.serviceCall();

        System.out.println("***********************");
        Phone p2 = new JarPhone(p1);
        System.out.println("升級為JarPhone手機");
        p2.serviceCall();
        System.out.println("***********************");

        Phone p3 = new ComplexPhone(p2);
        System.out.println("升級為ComplexPhone手機");
        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：發出聲音並震動提醒主人電話來了");
    }
}
package test11;

public class SimplePhone extends Phone {

    public void serviceCall() {
        System.out.println("SimplePhone：發出聲音提醒主人電話來了");
    }
}

3.注意程式設計規範。
