You should be able to specify the size of the gap(s) in the LayoutManager in the content pane of your JFrame.

My advice on your earlier thread still applies.

If you are using Netbean as IDE then remember this, that Netbean by default use GroupLayout. When you add components to panel, IDE add gaps. You can't change it so easily or better to say IDE won't allow this.

To overcome your problem, Right-click on your JFrame in IDE,
goto 'Set Layout' then choose any layout. If you really want panels border to touch each other or overlap then use absolute layout. But doing so you might face other problems, remember that.

thanks a lot prajin

If your using Absolute Layout, it may have solved your problem. But when you maximized the JFrame then all components stays where they are. That's not good look.
Try to go with Group Layout or other Layouts.
