Query: C++ comparison for C++ programers

I am a java programmer trying to learn C++, and find this book VERY hard to follow.Most of the syntax is not explained and too much time is spent explaining subtle details, rather than key concepts. Some of the real differences between c++ and java are clouded with confusing fragments of explanation, mixed with unexplained code.It seems to be more of a comparison or overview for C++ programmers than an introductory book for java developers.I am confused and left reading pages over and over again trying to make sense of this language. I think it would have been easier and quicker to just buy a c++ book, forgoing my java background.
