In the Swing component set, borders supercede Insets as the mechanism for creating a (decorated or plain) area around the edge of a component.

Usage Notes:

• Use EmptyBorder to create a plain border (this mechanism replaces its predecessor, setInsets).
• Use CompoundBorder to nest multiple border objects, creating a single, combined border.
• Border instances are designed to be shared. Rather than creating a new border object using one of border classes, use the BorderFactory methods, which produces a shared instance of the common border types.
• Additional border styles include BevelBorder, SoftBevelBorder, EtchedBorder, LineBorder, TitledBorder, and MatteBorder.
• To create a new border class, subclass AbstractBorder.
