Transfer Data

Question

i have 1 question
import java.io.*;
import java.net.*;
public class Client {
     public static void main (String args[]) {
          Input in;
          Output out;
          Socket socket;
          try {
               socket = new Socket("localhost", 10000);
               in = new Input (socket.getInputStream());
               out = new Output (socket.getOutputStream());
               int userChoice = 0;
               BufferedReader br = new BufferedReader (new InputStreamReader (System.in));
               BufferedReader rs = new BufferedReader (new InputStreamReader (System.in));
               System.out.println ("Connecting");
               //in.start ();
               //out.start ();
               do {
                    System.out.println ("1 - Add Contact");
                    System.out.println ("2 - View Contact");
                    System.out.println ("3 - Exit");
                    System.out.print ("Option: ");
                    userChoice = Integer.parseInt (br.readLine());
                    if (userChoice == 1) {
                         String strName, strCourse, tmp;
                         try {
                              System.out.print ("Enter name: ");
                              strName = rs.readLine();
                              System.out.print ("Enter course: ");
                              strNumber = rs.readLine ();
                              tmp = "INSERT INTO [YY]([YYname],[YYnumber]) VALUES ('" + strName + "', '" + strNumber + "')";
                              System.out.println(tmp);   // I want Transfer this to my server side code.
                         catch (Exception ex) {
                              System.err.println ("ERROR: " + ex.getMessage());
                    else if (userChoice == 2) {
                    else if (userChoice != 3) {
                         System.out.println ("ERROR: Invalid Choice.");
                    System.out.println ();
               } while (userChoice != 3);
          catch (Exception ex) {
               System.err.println (ex.getMessage());
}above is my client side code
i want the people key the data first
after that sent the tmp to my server side.
import java.io.*;
import java.net.*;
public class Server {
     public static void main (String args[]) {
          Input in;
          Output out;
          Socket socket;
          ServerSocket serverSocket;
          try {
               // setup server socket to listen on port 10000
               serverSocket = new ServerSocket (10000);
               socket = serverSocket.accept ();
               in = new Input (socket.getInputStream());
               out = new Output (socket.getOutputStream());
               in.start ();
               out.start ();
          catch (Exception ex) {
               System.err.println (ex.getMessage());
class Input extends Thread {
     String tmpData;
     BufferedReader br;
     Input (InputStream in) {
          br = new BufferedReader (new InputStreamReader (in));
          tmpData = "";
     public void run () {
          try {
               while ((tmpData = br.readLine ()) != null) {
                    System.out.println ("[REMOTE] " + tmpData);
          catch (Exception ex) {
               System.err.println ("ERROR: " + ex.getMessage ());
     public void close () {
          try {
               br.close ();
          catch (Exception ex) {
               System.err.println ("ERROR: " + ex.getMessage ());
class Output extends Thread {
     String tmpData;
     BufferedReader br;
     PrintStream ps;
     Output (OutputStream out) {
          ps = new PrintStream (out);
          br = new BufferedReader (new InputStreamReader (System.in));
     public void run () {
          try {
               while ((tmpData = br.readLine ()) != null) {
                    ps.println (tmpData);
                    ps.flush ();
                    if (tmpData.equalsIgnoreCase ("exit")) {
                         System.exit (0);
          catch (Exception ex) {
               System.err.println ("ERROR: " + ex.getMessage());
     public void close () {
          try {
               ps.close ();
               br.close ();
          catch (Exception ex) {
               System.err.println ("ERROR: " + ex.getMessage());
}

Answer 1

Problem is i dun know how to using the java.net to transfer it
I trying before
the server side there not response.
else is want me key in 2 time
if you open the client side this 2 thing
//in.start ();
//out.start ();
