Top 10 Websites to learn Java Programming for FREE

Java is one of the most popular programming languages. It was designed by James Gosling at Sun Microsystems and was released in May 1995.

Java is a high-level, general-purpose, object-oriented programming language designed with memory safety in mind. Its compiled code can run on any platform that supports Java without requiring recompilation, following the principle of “write once, run anywhere."

As of March 2025, Java 24 is the latest version, while Java 8, 11, 17, and 21 remain long-term support (LTS) versions that continue to receive maintenance updates.
