public class MyServerSocket {
  public static void main(String[] args) throws IOException{
    ServerSocket ssk;
    Socket sk;
    BufferedReader br;
    BufferedWriter bw;
    String inStr,outStr;
    ssk=new ServerSocket(8000);
    try{
      sk=ssk.accept();
      try{
        br=new BufferedReader(new InputStreamReader(sk.getInputStream()));
        bw=new BufferedWriter(new OutputStreamWriter(sk.getOutputStream()));
        inStr=br.readLine();
        outStr="hw ok! "+inStr;
        bw.write(outStr);
        bw.flush();
        br.close();
        bw.close();
      }
      catch(Exception e){

      }
      finally{
        sk.close();
      }
