Tree

Breaking things into hierarchies is natural. Think of your computer's file system, which employs drives, directories, subdirectories, folders, and files to keep things organized. With JTree we can create hierarchical organizations for any sort of graphical display.

The best way to describe JTree is as a cross between a list and an organizational chart. We're going to illustrate it first with a simple example and then with examples that increase in complexity (and thus become more realistic).
