Updating image

Question

I am having problems with following code
I need to create a mehod outside the GUi class constructor which will update the pic JPanel.
The update will just write numbers on top of the displayed picture on the Jpanel pic.
Sorry for the mess

public class GUI extends JFrame
final ImageIcon icon;
JPanel pic,menu, input;     
JTextArea area;
JTextField tf;
String tfs="";//string received from Text field
boolean Enter;//is true when user enters something.
int gameStage=0;//This variable represents the different game states
//0=the start getting no. of players.
//1=getting names of the players
//2=Occupying territory at the start of the Game
//3=Start of the turn
//4=Game finished player who rules all the map wins unless someone has left the game in which case player with most countries wins
public GUI()     {
super(" RISK-The world conquest game");                    
     army= new armies();
     Enter=false;
     icon = new ImageIcon("Risk.jpg");
     //initialise the three Panels
     //add Risk map to the Panel pic
     pic = new JPanel()     {               
public void paintComponent(Graphics g){     
          Dimension d = getSize();                    
g.drawImage(icon.getImage(), 0, 0, d.width, 402, null);     
          setOpaque( false );                    
super.paintComponent(g);          
     //add a textarea to the Menu Panel     
     menu=new JPanel();
     area=new JTextArea(8,71);
     area.setEditable(false);
     menu.add(area);
     //add a textfield to the Input Panel     
     input=new JPanel();
     tf=new JTextField(71);
     tf.addActionListener(new textListener());
     input.add(tf);
     //give the Panels a Border
     pic.setBorder(BorderFactory.createCompoundBorder(
BorderFactory.createLineBorder(Color.black),
pic.getBorder()));
menu.setBorder(BorderFactory.createCompoundBorder(
BorderFactory.createLineBorder(Color.black),
menu.getBorder()));
input.setBorder(BorderFactory.createCompoundBorder(
BorderFactory.createLineBorder(Color.black),
input.getBorder()));
     //Inititalise the Frame
     //add Panels to Frame
     Dimension size;
     //add menu
     getContentPane().add(menu);
     size=menu.getPreferredSize();
menu.setBounds( 0,404, size.width,size.height);
//add input
getContentPane().add(input);
size=input.getPreferredSize();
input.setBounds( 0,542, size.width,size.height);
//add Pic
     getContentPane().add(pic, BorderLayout.CENTER);
class textListener implements ActionListener{
public void actionPerformed(ActionEvent evt){
