In Need Of Divine Intervention

Question

Need some help with this. I can't seem to get the "browse" button to browse my PC for images in the Upload frame. The "Cancel" button is closing the entire programme instead of just the Upload frame.
Anyone know the problem? i just started java bout 3 months ago and still a noob at it =(

Answer 1

not got time to look much but replace the System.exit(0) with this.dispose() will close the frame instead of closing the whole application.
