I think I’m getting it... if I’m in 
east 
or 
west
, I get my preferred width but the 
height is up to the layout manager. And 
if I’m in 
north 
or 
south
, it’s just the 
opposite—I get my preferred height, but 
not width.
But what happens 
in the center region?
Components in the east and 
west get their preferred 
width.
Components in the north and 
south get their preferred 
height.
Components in the center get 
whatever space is left over, 
based on the frame dimensions 
(300 x 300 in this code).

When you put something 
in the north or south, it 
goes all the way across 
the frame, so the things 
in the east and west 
won’t be as tall as they 
would be if the north and 
south regions were empty.

FlowLayout cares 
about the flow of the 
components:
left to right, top to bottom, in 
the order they were added.
