我的一个小程序，上面是server

import java.io.*;
import java.net.*;

public class ChatClient {
        public static void main(String []args) {
                try {
                        Socket so = new Socket("127.0.0.1",6888);
                        BufferedReader br = new BufferedReader(new InputStreamReader(so.getInputStream()));
                        BufferedReader brw = new BufferedReader(new InputStreamReader(System.in));
                        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(so.getOutputStream()));
                        String c = brw.readLine();
                        bw.write(c);
                        System.out.println("client" + c);
                        while(c != "exit") {
                                bw.write(c);
                                bw.flush();
                                System.out.println("Client : " + c);
                                System.out.println("Server : " + br.readLine());    
                                c = brw.readLine();
                        }   
                        System.out.println("Chat Over");
                        br.close();
                        brw.close();
                        bw.close();
                }
                catch(Exception e) {}   
        }   
}

这是client，其实就是一个简单的，白痴的对话器，但是我怎么调试也不对，编译通过了，但是运行的时候一直卡在那里，感觉是io出问题了，大师们劳烦看看呗。非常感谢，实在是自己看不出来了。。。。。
