		try{
			Socket socket = new Socket("127.0.0.1",4000);
			System.out.println("输入你要说的话，如果要退出输入bye");
			BufferedReader sin = new BufferedReader(new InputStreamReader(System.in));
			PrintWriter os = new PrintWriter(socket.getOutputStream());
			BufferedReader is = new BufferedReader(new InputStreamReader(socket.getInputStream()));
			String readline;
			readline = sin.readLine();
			while(! readline.equals("bye")){
				os.println(readline);
				os.flush();
				System.out.println("CatClient:"+ readline);
				System.out.println("Server:" + is.readLine());
				readline = sin.readLine();
			}
			os.close();
			is.close();

}

//实现结果就是无论在那个程序所编译出来的对话框，你在里面输入你要说的话，就会在另外一个对话框显示出来。此两个小程序实现的是简单对话交流。

//该对话框的结束时输入bye，即会话结束。
