Java, one of the most popular programming languages, has undergone significant transformations since its inception. Its consistent updates have ensured its relevance in the ever-evolving tech world. From app development to enterprise solutions, Java has left an indelible mark. In this blog, we’ll explore the history of Java versions, highlighting key features and advancements with each release.
The Birth of Java
Java was created in 1995 by James Gosling and his team at Sun Microsystems. Initially called Oak, it was later renamed Java. Its primary goal was to develop platform-independent software, encapsulated in the famous slogan, “Write Once, Run Anywhere” (WORA).
