An object-oriented, high-level programming language introduced in 1995 by Sun Microsystems.
Known for its portability and ability to run applications across various platforms, including sports, social media, and audio/video services.

History of Java

Developed by James Gosling and his team (known as the Green Team) starting in June 1991.
Initially designed for small embedded systems, like set-top boxes; the original name was "Greentalk."
Renamed to "Oak" before its final name, Java, due to trademark issues in 1995.

Naming of Java

"Java" was chosen for its uniqueness and reflects the dynamic nature of the technology. It is named after the Indonesian island known for coffee production.
The name is not an acronym; it reflects a lively and engaging essence.

Major Releases and Features

Original release in 1995, followed by JDK 1.0 in January 1996.
Java quickly gained recognition, being named one of the Ten Best Products of 1995 by Time magazine.
Java has evolved with numerous versions, including Java SE 21, with a systematic approach to version releases (even versions in March, odd versions in September).
