public interface BorderInterface describing an object capable of rendering a border around the edges of a swing component. For examples of using borders see How to Use Borders, a section in The Java Tutorial.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.

g- the paint graphics -
x- the x position of the painted border -
y- the y position of the painted border -
width- the width of the painted border -
height- the height of the painted border
getBorderInsets
Insets getBorderInsets(Component c)
Returns the insets of the border.- Parameters:
