/**
* An implementation of a radio button -- an item that can be selected or
* deselected, and which displays its state to the user.
* Used with a {@link ButtonGroup} object to create a group of buttons
* in which only one button at a time can be selected. (Create a ButtonGroup
* object and use its <code>add</code> method to include the JRadioButton objects
* in the group.)
* <blockquote>
* <strong>Note:</strong>
* The ButtonGroup object is a logical grouping -- not a physical grouping.
* To create a button panel, you should still create a {@link JPanel} or similar
* container-object and add a {@link javax.swing.border.Border} to it to set it off from surrounding
* components.
* </blockquote>
* <p>
* Buttons can be configured, and to some degree controlled, by
* <code><a href="Action.html">Action</a></code>s. Using an
* <code>Action</code> with a button has many benefits beyond directly
* configuring a button. Refer to <a href="Action.html#buttonActions">
* Swing Components Supporting <code>Action</code></a> for more
* details, and you can find more information in <a
* href="http://docs.oracle.com/javase/tutorial/uiswing/misc/action.html">How
* to Use Actions</a>, a section in <em>The Java Tutorial</em>.
* <p>
* See <a href="http://docs.oracle.com/javase/tutorial/uiswing/components/button.html">How to Use Buttons, Check Boxes, and Radio Buttons</a>
* in <em>The Java Tutorial</em>
* for further documentation.
* <p>
* <strong>Warning:</strong> Swing is not thread safe. For more
* information see <a
* href="package-summary.html#threading">Swing's Threading
* Policy</a>.
* <p>
* <strong>Warning:</strong>
* 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&trade;
* has been added to the <code>java.beans</code> package.
* Please see {@link java.beans.XMLEncoder}.
