Elementary Java language features

Java is an object-oriented programming language, but there’s more to Java than programming with objects. This tutorial is the first of several introducing non-object-oriented features and syntax that are fundamental to the Java language. You’ll learn how to use comments, identifiers, types, literals, and variables in your Java programs. You’ll also learn why and how to document your code, and you’ll see how Java’s support for Unicode affects source code and compilation.
