[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。
