Java is a high-level, class-based, object-oriented programming language with a focus on minimizing implementation dependencies. It is a general-purpose programming language designed to enable programmers to write once and run anywhere (WORA), which means that compiled Java code runs on all systems that accept Java without the need to recompile. Typically, Java applications are compiled to bytecode, which may execute on any Java virtual machine (JVM), independent of the underlying computer architecture.
