What is Java?

Java is a high-level, class-based, object-oriented programming language developed by Sun Microsystems (now owned by Oracle) and released in 1995. Its most famous principle is "Write Once, Run Anywhere" (WORA) — Java code is compiled into platform-independent bytecode that runs on any device with a Java Virtual Machine (JVM). Java is statically typed, strongly typed, and manages memory automatically through garbage collection. It is one of the most widely used languages in the world, powering enterprise backends, Android apps, and large-scale distributed systems.
