javax.swing类 JRadioButtonjava.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.AbstractButton javax.swing.JToggleButton javax.swing.JRadioButton所有已实现的接口： ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstantspublic class JRadioButtonextends JToggleButtonimplements Accessible实现一个单选按钮，此按钮项可被选择或取消选择，并可为用户显示其状态。与 ButtonGroup 对象配合使用可创建一组按钮，一次只能选择其中的一个按钮。（创建一个 ButtonGroup 对象并用其 add 方法将 JRadioButton 对象包含在此组中。） 注：ButtonGroup 对象为逻辑分组，不是物理分组。要创建按钮面板，仍需要创建一个 JPanel 或类似的容器对象并将 Border 添加到其中以便将面板与周围的组件分开。 通过 Action 可以配置按钮，并进行一定程度的控制。对按钮使用 Action 有许多直接配置按钮所不及的优点。有关更多信息，请参阅支持 Action 的 Swing 组件，可以在 The Java Tutorial 中的 How to Use Actions 一节找到更多信息。 有关更多内容，请参阅 The Java Tutorial 中的 How to Use Buttons, Check Boxes, and Radio Buttons。 警告：Swing 不是线程安全的。有关更多信息，请参阅 Swings Threading Policy。 警告：此类的序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储，或适用于在运行相同 Swing 版本的应用程序之间进行 RMI（Remote Method Invocation，远程方法调用）。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeansTM 长期存储的功能。请参见 XMLEncoder。 另请参见：ButtonGroup, JCheckBox嵌套类摘要protected classJRadioButton.AccessibleJRadioButton 此类实现对 JRadioButton 类的可访问性支持。 从类 javax.swing.JToggleButton
