I have been tasked with porting a large Java codebase to the Android platform. The project makes extensive use of AWT which isn't' supported on Android.
I'm looking for a tool that lets me visualize all of the classes in the project. I'd like to be able to see all of the relationships between classes so that I can get a good idea of where to start the port.
If you have any suggestions that would help in this task I'd like to hear about them.
Netbeans has an OK reverse engineering tool which spits out a heaps of UML. I haven't used it in a while, but when I did it was a tad buggy.
I use Structure101 almost daily to visualize and understand our code base. A great tool and quite reasonably priced too.
This question has been touched at StackOverflow many times before and here are some links:
IntelliJ IDEA also has some tools to help, like Graphical Navigator in IDEA 8 and Code Navigator plugin.
There is an Eclipse plugin called Creole which you could also try. http://www.thechiselgroup.com/creole
