Question

I am a newbie in Java. I am trying to figure out how to work this code. It seems to me that it would be very useful if in the beginning I get the general structure of the code (which methods exists and how they are interrelated). For example I see that “main” uses “createAndShowGUI” which, in its turn, uses “addComponentsToPane” and so on. So, the code has kind of a tree structure and it would be nice if I can visualize this structure. Is there any software that can do it. Or, more specifically, can NetBeans do it?

Not sure about Netbeans, but in eclipse, you can right-click on a method and select “open call hierarchy” to get a tree view of methods that call the method you have selected, and at the top of the view is an icon to reverse this (“Show Callee Hierarchy”), which does pretty much what you want (except it shows only one method’s callees at a time).
