     Maybe the user will find the blank gray expanses soothing?
In any event, they're of his own making -- and he can un-make
them again if he finds them objectionable.  I sincerely doubt
that your efforts to protect him from his own faulty aesthetic
sense are worth while.

     Notice that this page is in a section whose title is
"Lesson: Layout Out Components *Within* a Container" [emphasis
mine].  You can control the sizes and layouts of things *inside*
a top-level container pretty closely, but the TLC itself is a
creature of the native windowing system, sized and positioned
(and decorated, hidden, revealed, ...) by that native system.
You're free to provide hints -- for example, the layout manager
of the frame's content pane can suggest the pane's dimensions --
but the native windowing system is not obliged to honor your
suggestions.  (This is viewed as a Good Thing, because it gives
your desktop app a fighting chance of being usable on a teeny-
tiny phone screen, for example.)

     To put it more simplistically: Java doesn't own "the screen"
and has no layout manager for it.
