What is Java?

Java is a widely-used, versatile programming language known for its simplicity and portability. Developed by Sun Microsystems, it's designed to run on various platforms without modification. Java's strength lies in its "write once, run anywhere" principle, making it ideal for web applications, mobile apps, and more. It's an object-oriented language, which means it organizes code around objects, making it easier to manage and maintain. Java's popularity is also attributed to its vast community support and extensive libraries, making it a go-to choice for developers aiming to build cross-platform applications.

Java was invented in 1991.Java got its name from a coffee-related reference

The story goes that the language's creators, James Gosling, Mike Sheridan, and Patrick Naughton, were brainstorming names when they spotted a coffee mug from the nearby break room. "Java" is a reference to the coffee brewed at the time by the company Moka, which was one of their favorites. The name was chosen because it sounded catchy and invoked a sense of energy and innovation, which they wanted to associate with the new programming language.
