Java is a high-level, object-oriented language built around the idea that code compiled once runs on any platform with a Java Virtual Machine. It is used for web applications, Android development, enterprise software, and games. A RunCode workspace gives you the JDK and VS Code preinstalled, so you can compile and run Java programs in under a minute.

Java compiles to bytecode that runs on the JVM, so the same compiled output works on any device or operating system that has a JVM installed. This portability has made Java a long-running choice for enterprise applications, Android apps, and backend services. Its object-oriented model and strong type system help structure large codebases and keep them maintainable over time.
