Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.

This comprehensive guide covers everything from Java basics to advanced topics. You'll learn about object-oriented programming, collections, generics, multithreading, I/O operations, networking, and more.
