Query: Too much fluff

About 65% of the material is useless fluff. Authors try to be funny and silly.I'm not an expert programmer. I took a few programming courses (C++) in college. It doesn't provide a good reference either.If you prefer technical books to be to the point this book isn't for you. If you've tried other Java books and it didn't help I guess this one will not hurt.It does have the information you need if you're willing to dig for it.
