@futurebird This is a good question and I wish I had an answer. The closest thing I have (it's an old book— it's been a while since I've done much Java) is "Bitter Java". It maybe is a slightly more advanced book, but. It is a book by a consultant who comes in to fix problems in other people's code. So it's all about "here's things people do wrong in Java— here's how to do them better". It's a very odd book, more philosophy than code, one of the best pieces of CS writing I've ever read actually.
