## Class EtchedBorder

- java.lang.Object
- - javax.swing.border.AbstractBorder
  - - javax.swing.border.EtchedBorder

- All Implemented Interfaces:
    Serializable, Border
  Direct Known Subclasses:
    BorderUIResource.EtchedBorderUIResource

      public class EtchedBorder
      extends AbstractBorder

  A class which implements a simple etched border which can either be etched-in or etched-out. If no highlight/shadow colors are initialized when the border is created, then these colors will be dynamically derived from the background color of the component argument passed into the paintBorder() method.

  Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`.
