代理模式实现婚介所

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。

 

 Female

public class Female implements NeedPerson{

    @Override
    public void findPerson() {
        // TODO Auto-generated method stub
     System.out.println("女生想找个陪伴自己的另一半");    
    }

    @Override
    public void showPerson() {
        // TODO Auto-generated method stub
        System.out.println("女生的信息:白富美");
    }

    @Override
    public void showMateSelectionRequirements() {
        // TODO Auto-generated method stub
        System.out.println("女生的要求:高大帅气，有钱多金");
    }

    @Override
    public void setLevel(int level) {
        // TODO Auto-generated method stub
        
        
    }

}

MarriagAgency

public class MarriageAgency implements NeedPerson{
    private Female f=new Female();
    private int level=0;
    @Override
    public void findPerson() {
