JSeparator

JSeparator is a Java class that provides a visual horizontal or vertical line, often used as a separator between other components in a graphical user interface. It is part of the Swing GUI toolkit, which is a standard part of the Java Development Kit (JDK). JSeparator is a lightweight component, meaning it delegates its painting and event handling to its parent container. Its primary purpose is to visually group or delineate elements within a user interface, contributing to better organization and readability. A JSeparator can be configured to be either horizontal or vertical by setting its orientation. The default orientation is horizontal. It can be added to containers like JFrames, JDialogs, or JPanels, typically using layout managers. While it doesn't have interactive functionality, its presence aids in the logical structuring of the UI. Developers can customize its appearance to some extent, although extensive styling is usually handled by more complex components. It is commonly used in menus, toolbars, and within panels to separate related sets of controls.
