Every content pane is initialized to use a BorderLayout. As Using Top-Level Containers explains, the content pane is the main container in all frames, applets, and dialogs. A BorderLayout places components in up to five areas: top, bottom, left, right, and center. All extra space is placed in the center area. Tool bars that are created using JToolBar must be created within a BorderLayout container, if you want to be able to drag and drop the bars away from their starting positions.
For further details, see How to Use BorderLayout. The BoxLayout class puts components in a single row or column. It respects the components' requested maximum sizes and also lets you align components. For further details, see How to Use BoxLayout. The CardLayout class lets you implement an area that contains different components at different times. A CardLayout is often controlled by a combo box, with the state of the combo box determining which panel group of components the CardLayout displays.
An alternative to using CardLayout is using a tabbed pane , which provides similar functionality but with a pre-defined GUI. For further details, see How to Use CardLayout. FlowLayout is the default layout manager for every JPanel. It simply lays out components in a single row, starting a new row if its container is not sufficiently wide.
