A split pane is a lightweight container that allows you to arrange two components (only two) side by side horizontally or vertically in a single pane. The display areas of both the components can also be adjusted at the runtime by the user. A split pane is an object of JSplitPane class.

Some of the constructors defined by JSplitPane class are as follows.

JSplitPane ()

JSpliPane(int orientation, boolean continuousLayout)

JSplitPane(int orientation, Component TopOrLeft,BottomOrRight)

JSplitPane(int orientation, boolean continuousLayout, Component TopOrLeft, Component BottomOrRight)


orientation specifies how components will be arranged - can have one of the two values:


continuousLayout can have one of the two values: true,if the components are resizable

when divider is moved, otherwise false (default value)

TopOrLeft specifies the object to be placed at top or left

BottomOrRight specifies the object to be placed at bottom or right
