## javax.swing.border
Class LineBorder

    java.lang.Object
      javax.swing.border.AbstractBorder
          javax.swing.border.LineBorder

All Implemented Interfaces:
  Serializable, Border

Direct Known Subclasses:
  BorderUIResource.LineBorderUIResource

    public class LineBorder

extends AbstractBorder

A class which implements a line border of arbitrary thickness and of a single color.

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 JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

Field Summary
`protected Color` | `lineColor`
`protected boolean` | `roundedCorners`
`protected int` | `thickness`
