代理模式之静态代理

//租房的抽象接口
public interface Rent {
	public void rent();
}

//房东,被代理的真实角色
public class Host implements Rent{
	public void rent(){
		System.out.println("房东出租房屋");
	}
}

	//代理角色
public class Proxy {
	private Host host;
	public Proxy() {
	}
	public Proxy(Host host) {
		super();
		this.host = host;
	}
//	public void setHost(Host host) {
//		this.host = host;
//	}
	//中介租房的方法
	public void rent(){
		seeHouse();
		host.rent();
		fare();
	}
	//看房
	public void seeHouse(){
		System.out.println("带房客看房");
	}
	//收取中介费
	public void fare(){
		System.out.println("收取一波中介费");
	}
}

		//顾客
public class Client {
	public static void main(String[] args) {
		Host host = new Host();
		Proxy proxy = new Proxy(host);
