I (like a lot of the people on this board) learned c++ then java. Learning java after learning c++ is easy... But I've talked to people who went from java to c++, and said it was a real pain to learn, especially since they didn't know c.

And BTW, C/C++ syntax is very much like java, anyone not able to learn it should seriously reconsider whether they really want to become programmers.
Your best bet of course is to take a c++ class or two, and make sure they teach you oop, not c using cout (the way some people teach c++).
It won't be that hard for you to pick up c++ since you already know java.
