Java's journey began in 1991 at Sun Microsystems (later acquired by Oracle) with a project called "Green." Initially conceived for interactive television, the project didn't take off as planned. However, the team, led by James Gosling, recognized the potential of their platform-independent language, which they initially called "Oak" (later renamed Java).

Key Milestones:

• 1995: Java 1.0 Released: This marked the official launch of Java, emphasizing its "Write Once, Run Anywhere" (WORA) capability. It gained rapid popularity due to its platform independence and suitability for web applications.
• 1998: Java 2 (J2SE 1.2): Introduced significant enhancements, including the Swing GUI toolkit and Collections Framework, making Java more versatile for desktop and enterprise applications.
• 2004: Java 5 (J2SE 5.0): Added generics, annotations, and autoboxing/unboxing, improving code readability and reducing boilerplate code.
• 2006: Java 6: Focused on performance improvements and added support for scripting languages.
• 2011: Java 7: Introduced new language features like string switch statements and try-with-resources.
• 2014: Java 8: A major release that introduced lambda expressions, streams API, and the new Date and Time API, revolutionizing Java development.
• 2017: Java 9: Introduced the module system (Project Jigsaw), enhancing modularity and security.
• 2018: Java 10: Introduced local variable type inference (var keyword).
• 2019: Java 11: The first long-term support (LTS) release under the new release cadence, focusing on performance and security.
• Present: Java continues to evolve with regular updates and new features, maintaining its position as a leading programming language for enterprise applications, Android development, and more.

Impact on the Indian IT Industry:

Java has played a pivotal role in the growth of the Indian IT industry. Its platform independence, scalability, and large talent pool have made it a preferred choice for many Indian IT companies. Java developers in India are highly sought after, contributing significantly to the global software development landscape.
