Unfortunately, you're a C++ programmer, or maybe a Python programmer. How are you going to get up to speed in a hurry? There are lots of Java books for beginners, telling you all about what a computer is, and how it represents everything in bits. You don't need that. At the other extreme, there are thousand-page tomes that you aren't going to get through in a few days, if ever. You need something in between. This book is intended to fill that gap. It's written for the programmer who doesn't need to be taught how to program, just how to do it in Java-and who needs to get started in a hurry. Java is covered from the inside out. First, all the things that go inside a class, most of which are practically identical to C++. After that, all the various and complicated kinds of classes and interfaces, and how they relate to each other in large-scale programs.
