实验14：代理模式
实验14：代理模式
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、理解代理模式的动机，掌握该模式的结构；
2、能够利用代理模式解决实际问题。
[实验任务一]：婚介所
婚介所其实就是找对象的一个代理，请仿照我们的课堂例子“论坛权限控制代理”完成这个实际问题，其中如果年纪小于18周岁，婚介所会提示“对不起，不能早恋！”，并终止业务。
实验要求：
1. 提交类图；
2. 提交源代码；
JAVA
public abstract class Center
{
protected String name;
public Center(String name){this.name=name;}
public abstract void findlove(Person person);
}
public class Marry extends Center
{
public Marry(String name){super(name);}
public void findlove(Person person)
{
if(person.getAge()<18)
{
System.out.println(name+":"+person.getName()+",对不起！不能早恋！");
}
else if(person.getAge()<100)
{
System.out.println(name+":"+person.getName()+",我们会为您找到合适的伴侣！");
}
else
{
System.out.println(name+":"+person.getName()+",对不起！您年龄太大了！");
}
}
}
public class Person {
protected String name;
protected int age;
public Person(String name,int age)
{
this.name=name;
this.age=age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
public class Client
{
public static void main(String args[])
{
Center center1,center2;
center1=new Marry("婚介");
center2=new Marry("婚介");
Person b1=new Person("喜羊羊",29);
Person b2=new Person("美羊羊",16);
center1.findlove(b1);
center2.findlove(b2);
}
}
C++

Person b2=new Person("美羊羊",16);
center1.findlove(b1);
center2.findlove(b2);
}
}
3. 注意编程规范。
