所有已實作的介面：

ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, MenuElement, SwingConstants

public class JRadioButtonMenuItem
extends JMenuItem
implements Accessible

一個單選按鈕選單項的實作。JRadioButtonMenuItem 是屬於一組選單項中的一個選單項，該組中只能選擇一個項。被選擇的項顯示其選擇狀態。選擇此項的同時，其他任何以前被選擇的項都切換到未選擇狀態。要控制一組單選按鈕選單項的選擇狀態，請使用 ButtonGroup 物件。

通過 Action 可以配置選單項，並進行一定程度的控制。對選單項使用 Action 有許多直接配置選單項所不及的優點。有關更多資訊，請參閱支持 Action 的 Swing 元件，可以在 The Java Tutorial 中的 How to Use Actions 一節找到更多資訊。

有關更多內容和範例，請參閱 The Java Tutorial 中的 How to Use Menus 一節。

警告：Swing 不是執行緒安全的。有關更多資訊，請參閱 Swing's Threading Policy。

警告：此類別的序列化物件與以後的 Swing 版本不相容。當前序列化支持適用於短期存儲，或適用於在運行相同 Swing 版本的應用程序之間進行 RMI（Remote Method Invocation，遠端方法調用）。從 1.4 版本開始，已在 java.beans 套件中添加了支持所有 JavaBeans^TM 長期存儲的功能。請參見 XMLEncoder。
