Cscope supports C, C++, and Java. It should work the same for all three. You need to build your cscope database, and for Java this will require getting a list of files using find, and then use :cs in vim to load it. I primarily write C and I put the build commands in my Makefiles for ctags and cscope. The Linux kernel also has this feature as well. If you go into the kernel source you can just run `make tags` and `make cscope` and it lets you browse the 100s of millions of lines of kernel source with either.
