String serversen;
public void go(){
try{
     ServerSocket serverSock=new ServerSocket(6789);
     while(true) {
     Socket sock=serverSock.accept();
     BufferedReader inFromClient=new BufferedReader(new InputStreamReader(sock.getInputStream()));
     BufferedReader inFromuser=new BufferedReader(new InputStreamReader(System.in));
     DataOutputStream outToClient=new DataOutputStream(sock.getOutputStream());
     clientsen=inFromClient.readLine();
     System.out.println("From Client: "+clientsen);
     System.out.println("Reply mess to Client");
     serversen=inFromuser.readLine();
     outToClient.writeBytes(serversen+'\n');
} catch(IOException ex) {
     ex.printStackTrace();
public static void main(String[] args) {
     Server s = new Server();
     s.go();

          String Sen;
          String modsen;
          BufferedReader inFromUser=new BufferedReader(new InputStreamReader(System.in));
Socket clientSocket=new Socket("192.168.1.2",6789);
          DataOutputStream outToServer=new DataOutputStream(clientSocket.getOutputStream());
          BufferedReader inFromServer=new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
          System.out.println("Enter the mess to be sent to server");
          Sen=inFromUser.readLine();
          outToServer.writeBytes(Sen + '\n');
          modsen=inFromServer.readLine();
          System.out.println("FROM SERVER: " +modsen);
          clientSocket.close();
please send me the solution code for my problem...
