Java was initiated by James Gosling and his team back in 1991 under the Green Project. It all started with the goal of creating a platform-independent language.
That's interesting! Why was it called the Green Project?
Great question! The name reflected the fresh, new ideas they aimed to bring into the programming world. Does anyone know what was Java originally called?
I think it was called Oak!
Correct! It was renamed to Java later, inspired by Indonesian coffee. It's always fun to learn about those small details in programming history.
Java's Official Release

In 1995, Java was officially released as Java 1.0 by Sun Microsystems. Can anyone tell me what significant feature Java introduced with this release?
I think it was the 'write once, run anywhere' capability!
Absolutely! That capability stemmed from the Java Virtual Machine. It meant Java code could run on any platform with the JVM present, which is a huge advantage!
So, thatβs how it became so popular among developers.
Exactly! This portability is a key reason why Java has remained relevant over the years.

In 2009, Oracle Corporation acquired Sun Microsystems. This event marked a significant turning point in Java's history. What do you think this acquisition meant for Java?
Maybe they brought new resources to improve Java?
Exactly! Oracle has continued to maintain and evolve Java. The framework has seen versions like Java 8, 11, and beyond, introducing advanced features like lambda expressions.
So, the version updates must have made Java more powerful for developers!
Right! Each version has built on its capabilities, ensuring its growth and relevance in the tech industry.
Java's Continuous Evolution

Java has evolved significantly through its various versions. Besides lambda expressions, can anyone name another feature introduced in recent versions?
How about modules?
Correct! Modules were introduced in Java 9, further enhancing code organization and encapsulation.
What about records? I heard those were also new.
You're right again! Records were added in Java 14 to simplify data handling. Features like these keep Java modern and adaptable to current programming needs.

Quick Overview
Standard
Java was initiated by James Gosling and his team in 1991, officially released in 1995, and has evolved through numerous versions. Originally named 'Oak,' Java is now maintained by Oracle, having been acquired in 2009, and continues to innovate with features like lambda expressions and modules.

History and Evolution of Java
Java, a high-level, object-oriented programming language, was developed in the early 1990s under the Green Project initiated by James Gosling and his team at Sun Microsystems. It was officially released as Java 1.0 in 1995, establishing the foundation for Java's journey. Over the years, Java has gone through significant changes, including updates that brought numerous new features and mechanisms, enhancing its performance and usability. In 2009, Oracle Corporation acquired Sun Microsystems, taking over the maintenance and development of Java. Today, Java continues to evolve with various versions, including Java 8, 11, and 17, each introducing features such as lambda expressions, modules, and records. An interesting fact about Java is that it was initially called Oakβnamed after an oak tree outside Gosling's officeβbut was later renamed Java, inspired by Indonesian coffee.

β 2009: Sun Microsystems was acquired by Oracle Corporation, which now maintains Java.
Detailed Explanation
In 2009, Oracle Corporation acquired Sun Microsystems. This acquisition was significant because Oracle took over the development and maintenance of Java, ensuring its continued evolution and support in the tech world.
Examples & Analogies
Imagine a beloved restaurant getting new owners. While the restaurant's name and menu stay the same, the new owners might introduce new dishes and improve the dining experience. In a similar way, Oracle's acquisition helped improve Java while maintaining its core values.

Fun fact: Java was originally called Oak but was later renamed Java, inspired by Java coffee from Indonesia.
Detailed Explanation
Originally, Java was named Oak, but this name was changed to Java. The name was inspired by Java coffee, as the creators wanted a name that conveyed energy and vitality, reflecting the dynamic nature of the language.
Examples & Analogies
Just like how a person might change their name to fit their personality better, Java's name change was a way to capture the essence of the programming language. Itβs akin to how a product might be rebranded to appeal to a certain audience or market.
