Dragging handle in Java Swing

Question

I can't seem to figure out how to make a resize drag handle in Java Swing. If you're not sure what I mean, open up the "Ask Question" page on this website and look at the bottom of the text area. It has a bar which you can drag in order to change the size of the area. I'm looking for a way to do this in Java Swing. I don't even know where to look at this point.

Any help would be appreciated.

In my opinion, the drag handle that's used on the Stack Overflow posting form most closely resembles that of a vertical JSplitPane, both in appearance and functionality.
