Java is one of the most widely used programming languages and computing platforms in the world. Developed by Sun Microsystems (now owned by Oracle Corporation), Java is designed to be simple, portable, and secure, making it a popular choice for building cross-platform applications. The philosophy behind Java is “Write Once, Run Anywhere,” which means that once Java code is compiled into bytecode, it can run on any platform that has a compatible Java Virtual Machine (JVM), making it highly versatile.
