Java Swing BorderLayout

This tutorial will teach us about Java Swing BorderLayout with an example demo program. A border layout lays out a container, arranging and resizing its components to fit in five regions:

NORTH
SOUTH
EAST
WEST
CENTER

BorderLayout also supports relative positioning in the container:

PAGE_START
PAGE_END
LINE_START
CENTER
LINE_END
