OpenJDK 1.22 · javax.swing.border.Border

Interface 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 supersede 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.
