实验11：装饰模式
本次实验属于模仿型实验，通过本次实验学生将掌握以下内容：
1、理解装饰模式的动机，掌握该模式的结构；
2、能够利用装饰模式解决实际问题。

[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；
public interface Phone {
void phoneFunction();
}
public class SimplePhone implements Phone {
@Override
public void phoneFunction() {
System.out.println("SimplePhone: Ringing");
}
}
public abstract class PhoneDecorator implements Phone {
protected Phone phone;

public PhoneDecorator(Phone phone) {
this.phone = phone;
}

public void phoneFunction() {
phone.phoneFunction();
}
}
public class JarPhone extends PhoneDecorator {
public JarPhone(Phone phone) {
super(phone);
}

@Override
public void phoneFunction() {
super.phoneFunction();
jarFunction();
}

private void jarFunction() {
System.out.println("JarPhone: Vibrating");
}
}

public class ComplexPhone extends PhoneDecorator {
public ComplexPhone(Phone phone) {
super(phone);
}

@Override
public void phoneFunction() {
super.phoneFunction();
complexFunction();
}

private void complexFunction() {
System.out.println("ComplexPhone: Flashing light");
}
}
public class Client {
public static void main(String[] args) {
Phone phone = new SimplePhone();
System.out.println("SimplePhone:");
phone.phoneFunction();

System.out.println("\nJarPhone:");
Phone jarPhone = new JarPhone(phone);
jarPhone.phoneFunction();

System.out.println("\nComplexPhone:");
Phone complexPhone = new ComplexPhone(jarPhone);
complexPhone.phoneFunction();
}
}
3.注意编程规范。
