Thread won't run

Question

in my program i want a thread name getdata to start, but it does not. if it did a statement in system would say so. Any help in getting the thread to run would be great thanks. Here is the code:
public void listenSocket() {
     if ( connected==("2") ) {
//Create socket connection
     try{
       socket = new Socket(ipaddress, 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);
               connected = "1";
               Thread getdata = new Thread();
               getdata.start();
     else {
          try{
                socket = new Socket(ipaddress, 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);
     senddata();
public void run()
          if( getdata == Thread.currentThread() )
               System.out.println("running getdata thread");
               friendtypingLabel.setText("running get data");
               getdatamethod();
}

I believe you really have to read the API about Thread this is not the way at all how you can create a new Thread.
Thread getdata = new Thread();
getdata.start();Create a new Thread object with itself as its underlying Runnable. Therefore when you start it, it process the run() method of Thread class which is empty. You must create a class which extends Thread and overload its run method instead or create a class that implements Runnable and create the new Thread with:
Thread t = new Thread(myRunnable);
t.start();
