	public static void main(String[] args) {
		Socket s=null;
		PrintStream ps=null;
		while(true){
		try {

			BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
			String str=br.readLine();
			ps.println(str);
			ps.flush();

			System.out.println("服务器端发回的数据为:"+brin.readLine());
		} catch (IOException e) {
