JSplitPane Example
A JSplitPane contains two JPanels, horizontally or vertically aligned. In this JSplitPane example we align them vertically.
A central bar allows the user to adjust the amount showing in each JSplitPane. This puts the user in control of screen resource management and is to be found in tools such as email programs in which long lists of information (perhaps names or addresses) need to be dealt with.
