JToolBar

JToolBar is a Swing component in Java that provides a container for a row or column of buttons or other controls, typically used for quick access to frequently used actions. It is part of the javax.swing package. A JToolBar can be placed within a JFrame or other container and can be docked to different sides of its parent window or floated as a separate window.

The primary purpose of a JToolBar is to present a set of buttons that trigger specific operations within an application. These buttons often display icons to visually represent the action they perform. JToolBar components are commonly used in graphical user interfaces to offer a convenient and accessible way for users to interact with the application's features without needing to navigate through menus.

Key features of JToolBar include its ability to be made floatable, allowing users to detach it from its docking location and move it around the screen. It also supports adding separators between groups of buttons to improve visual organization. JToolBar can contain not only JButtons but also other Swing components like JComboBoxes or JLabels, providing flexibility in its design. The layout of components within a JToolBar is managed by an internal LayoutManager, typically a BoxLayout.
