代码出现问题，请高手指点

Question

我想从键盘读取字符串发送给服务器端,然后做个简单的处理(反序排列),然后回传给客户端,但是客户端这边却一直得不到回传的数据，请高手指点下，是哪里写错了. //服务器端

改好了，关键是你的readline有问题，因为你readLine()进来的是没有换行符的，所以发过去对方readline一直在等待换行，在write()后面加个newLine()就好了，其他的还修改了一些小毛病，楼主自己看吧。服务端：import java.net.Socket;
import java.net.ServerSocket;
import java.io.*;public class Servicer implements Runnable
{
    Socket s;
    
    public Servicer(Socket s)
    {
        this.s = s;
    }
    
    public void run()
    {
        BufferedWriter bw = null;
        BufferedReader br = null;
        try
        {
            bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
            br = new BufferedReader(new InputStreamReader(s.getInputStream()));
            
            while (true)
            {
                String str = br.readLine();
                if (str.equalsIgnoreCase("quit"))
                {
                    break;
                }
                bw.write(str + "---->");
                str = new StringBuffer(str).reverse().toString();
                bw.write(str);
                bw.newLine();
                bw.flush();
            }
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
        finally
        {
            try
            {
                if(bw != null)
                {
                    bw.close();
                }
                if(br != null)
                {
                    br.close();
                }
                if(bw != null)
                {
                    s.close();
                }
            }
            catch(IOException e1)
            {
                
            }
