实现的所有接口

ImageObserver ， MenuContainer ， Serializable ， Accessible ， SwingConstants

已知直接子类：

JPopupMenu.Separator ， JToolBar.Separator
```
@JavaBean(defaultProperty="UI",
          description="A divider between menu items.")
public class JSeparator
extends JComponent
implements SwingConstants, Accessible
```
JSeparator提供了一个用于实现分隔线的通用组件 - 最常用作菜单项之间的分隔符，将它们分解为逻辑分组。而不是使用JSeparator直接，你可以使用JMenu或JPopupMenu addSeparator方法来创建并添加一个分隔符。 JSeparator s也可以在GUI的其他地方使用，只要有视觉分隔符。
有关更多信息和示例，请参阅“Java教程”中的 How to Use Menus部分。

警告： Swing不是线程安全的。有关更多信息，请参阅Swing's Threading Policy 。

警告：此类的序列化对象与以后的Swing版本不兼容。当前的序列化支持适用于运行相同版本Swing的应用程序之间的短期存储或RMI。从1.4开始， java.beans软件包中添加了对所有JavaBeans java.beans长期存储的支持。请参阅XMLEncoder 。

从以下版本开始：
