public class Server extends JFrame
{


     private JTextField textConnection;
     private JLabel labelConnection;

     public Server()

     {

           container = getContentPane() ;

           container.add(labelConnection );
           textConnection = new JTextField(15) ;
           container.add(textConnection);
           textConnection.setText("Disconnected");

          setSize ( 200,400) ;
          setVisible(true);

          try
          {
               //creating server socket binding at port # 3000
