Do not use setSize(). Instead if possible let the components set their own sizes based on their need and the layout manager. You can use setPreferredSize(...) if you must set a size of a component. Always call pack() on the JFrame after adding all components which tells the layout managers to do their thing, then call setLocationXXX(...) then call setVisible(true) in that order.

k thnx. but i like to make JFrame full screen. Thats why i was asking..
