How can i display a number on a jlabel.

If you're going to put it in a jlabel, it doesn't have to be numeric because both TextFields and JLabels work with Strings. However, if you need the number for a calculation, you'll need to parse it with one of the wrapper classes - Integer, Float, Double, etc...

okay i got it now, but how can i send the value of the jtextfield to a jlabel.

 public void actionPerformed(ActionEvent e)
    {
        
   if (e.getSource() == chk1){
       numcf1 = Integer.parseInt(txttall.getText());
            
       
        }

You have already been told. Both textfields and labels use Strings. So all you need to do is get the String from one and pass it to the other.

JLabel (Java Platform SE 6)

Have you looked at the API at all? Namely the .setText() method?
