Exactly. I seldom use it for my own code, can't remember the last time I did it but stepping through some huge undocumented Java codebase with Aspects oriented programming in it like Spring AOP (where the actual code that runs in that random function invocation is in some .xml file defined but not directly in the code) saved me a lot of time.

Also debuggers display contents of variables very nicely while stepping through code - for me a good way to verify my assumptions after reading a certain piece of code, just set a breakpoint and see if it's actually works that way - I'm often surprised.

Maybe it's not really required for C / low-level code but if you are wrangling complex Java codebases it's a very nice tool to have in the toolbox.
