What is Java?

Java is a general-purpose programming language designed to be platform-independent, allowing code to run on any device with a Java Virtual Machine (JVM). Created by James Gosling at Sun Microsystems in 1995, it's widely used for web applications, mobile apps (Android), and enterprise software.
