Whats wrong, why doesnt the thread start?

Question

Below is my code for the part of my program, which creates a thread for every client that connects to a server in an instant messenger program. What the thread does it constantly recieves any data sent to the server, so that it therefore displays it on its own area of the screen. For some reason...this thread does not want to start. Any help would be incredibly appreciated. So heres the code:
class SocketClient extends JFrame implements Runnable {
     Socket socket = null;
   PrintWriter out = null;
   BufferedReader in = null;
          String text = null;
          Thread getdata;
   SocketClient(){
     public void listenSocket() {
     if ( connected==("2") ) {
//Create socket connection
     try{
       socket = new Socket("0.0.0.0", 4444);
                    System.out.println("Connected to self");
       out = new PrintWriter(socket.getOutputStream(), true);
       in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
     } catch (UnknownHostException e) {
       System.out.println("Unknown host: host your connecting to");
       System.exit(1);
     } catch  (IOException e) {
       System.out.println("No I/O");
       System.exit(1);
               connected = "1";
     else {
          try{
                socket = new Socket("0.0.0.0", 4444);
       out = new PrintWriter(socket.getOutputStream(), true);
       in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
     } catch (UnknownHostException e) {
       System.out.println("Unknown host: host your connecting to");
       System.exit(1);
     } catch  (IOException e) {
       System.out.println("No I/O");
       System.exit(1);
     if (thisclient==(1))
               System.out.println("in thisserver");
               Thread getdata = new Thread();
                         getdata.start();
                         thisclient = 2;
     senddata();
public void senddata() {
     //Send data over socket
     System.out.println("in send data method");
     friendtypingLabel.setText("in send data");
          String text = messageArea.getText();
          out.println(text);
       messageArea.setText(new String(""));
//Receive text from server
public void run()
          if(getdata == Thread.currentThread() )
               System.out.println("running getdata thread");  // if the thread was running this would be written to system but it isnt
               friendtypingLabel.setText("running get data");
               getdatamethod();
public void getdatamethod() {
     //Send data over socket
//Receive text from server
while(true) {
       try{
       String line = in.readLine();
          messlistArea.append("Message Client:" + line + "\n");
       } catch (IOException e){
      System.out.println("Read failed");
             System.exit(1);
          try { Thread.sleep(2000); }
               catch(InterruptedException e) {}
}

k...well ive made it so that the client can see what they have just sent....but i cant seem to make is so that the can see wot the server and wot other clients have sent...here is some update code:
class SocketClient extends JFrame implements Runnable {
     Socket socket = null;
   PrintWriter out = null;
   BufferedReader in = null;
          String text = null;
   SocketClient(){
     public void listenSocket() {
     if ( connected==("2") ) {
//Create socket connection
     try{
       socket = new Socket("0.0.0.0", 4444);
                    System.out.println("Connected to self");
       out = new PrintWriter(socket.getOutputStream(), true);
       in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
     } catch (UnknownHostException e) {
       System.out.println("Unknown host: host your connecting to");
       System.exit(1);
     } catch  (IOException e) {
       System.out.println("No I/O");
       System.exit(1);
               connected = "1";
     else {
          try{
                socket = new Socket("0.0.0.0", 4444);
       out = new PrintWriter(socket.getOutputStream(), true);
       in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
     } catch (UnknownHostException e) {
       System.out.println("Unknown host: host your connecting to");
       System.exit(1);
     } catch  (IOException e) {
       System.out.println("No I/O");
       System.exit(1);
     if (thisclient==(1))
               System.out.println("in thisserver");
               getdata = new Thread(this);
                                                                                                                                            // if this is the client, then start the getdata
                         getdata.start();                                                                           // thread
                         thisclient = 2;
                         getdata.equals(Thread.currentThread());
     senddata();
public void senddata() {
     //Send data over socket
     System.out.println("in send data method");
     friendtypingLabel.setText("in send data");
          String text = messageArea.getText();
          out.println(text);
       messageArea.setText(new String(""));
//Receive text from server
public void run()                                                   // runs the thread getdata
System.out.println("Thread is " + Thread.currentThread());
          if(getdata.equals(Thread.currentThread()) )
               getdatamethod();
public void getdatamethod() {                      // method for the getdata thread
     //Send data over socket
//Receive text from server
while(true) {
System.out.println("Run getdata");
       try{
                 String line = in.readLine();
                    if (line != null) {
          messlistArea.append("Message Client:" + line + "\n");
                         }catch (IOException e){
                          System.out.println("Read failed");
                  System.exit(1);
          try { Thread.sleep(2000); }
               catch(InterruptedException e) {}
