public class udpClient extends Applet {
      Label lblCommon =  new Label("Text Here");
      Panel pTop = new Panel();
      Button bEnter = new Button("Enter");
      TextField txtChat      = new TextField(20);
      List lst = new List(4, false);
      
      public void init() {
          
            class BL implements ActionListener {
                  public void actionPerformed(ActionEvent e){
                        lst.add(txtChat.getText());
                        lst.add(Integer.toString(lst.getItemCount()));
                        lst.select(lst.getItemCount());
                        lst.makeVisible(lst.getItemCount());
                         
                  }
            }
            
            BL a = new BL();
            bEnter.addActionListener(a);
            
            resize(320,400);
            
          setLayout(new BorderLayout());
          add(pTop,BorderLayout.NORTH) ;
                
                pTop.add(lblCommon);
                pTop.add(txtChat);
                pTop.add(bEnter);
          
          add(lst,  BorderLayout.CENTER);
