- 代理设计就是为其他对象提供一种代理以控制对这个对象的访问
package exer;
public class NetWorkTest {
public static void main(String[] args) {
Server server=new Server();
ProxyServer proxyServer=new ProxyServer(server);
proxyServer.browse();
}
}
interface NetWork{
public abstract void browse();
}
//被代理类
class Server implements NetWork{
public void browse(){
System.out.println("真实的服务器访问网络");
}
}
//代理类
class ProxyServer implements NetWork{
private NetWork work;
public ProxyServer(NetWork work){
this.work=work;
}
public void check(){
System.out.println("联网之前的检查工作");
}
public void browse(){
check();
work.browse();
}
}
