Xah's Java Tutorial

This is a brief tutorial on Java the language for those professional programers who may not have had experience with Object Oriented methodology, or those who wish to have a no-frills introduction to Java. This tutorial is example based, and explains the java language concretely. It explains how the language's various keywords and constructs effect the source code's meaning. (Think of it as a practical mathematical treatment) This tutorial does not use metaphors (such as “fruits→(bananas, apples)” for hierarchy) that are commonly practiced in most other Java books, nor do we try to tell you what's supposedly good practices and benefits of “software engineering” and OOP. We also avoid computer scientist's perspective with concepts such as “memory allocation”, “garbage collection”, “stacks”, “pointers/references”.

In summary, if you are a programer familiar with a high-level language (aka scripting language) such as PHP, Javascript, Python, Mathematica, you'll find this tutorial to the point.
