      public interface 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 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.

    `BorderFactory`, `EmptyBorder`, `CompoundBorder`

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `Insets` | `getBorderInsets(Component c)` Returns the insets of the border.
    `boolean` | `isBorderOpaque()` Returns whether or not the border is opaque.
    `void` | `paintBorder(Component c, Graphics g, int x, int y, int width, int height)` Paints the border for the specified component with the specified position and size.

- - ### Method Detail

    - #### paintBorder

          void paintBorder(Component c,
                           Graphics g,
                           int x,
                           int y,
                           int width,
                           int height)

      Paints the border for the specified component with the specified position and size.
      Parameters:
        `c` - the component for which this border is being painted
        `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:
        `c` - the component for which this border insets value applies

    - #### isBorderOpaque

          boolean isBorderOpaque()

      Returns whether or not the border is opaque. If the border is opaque, it is responsible for filling in it's own background when painting.
