Java Tutorial
Java is an exceptionally powerful, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. Java follows the "Write Once, Run Anywhere" (WORA) philosophy, which means compiled Java code can run on all platforms that support Java without the need for recompilation. In this guide, we will cover the core syntax of Java, its object-oriented nature, and how to write and run Java programs online.
