"Java" generally refers to a combination of three things:
the Java programming language (a high-level, object-oriented
programming language); the Java Virtual Machine (a
high-performance virtual machine that executes bytecodes on
a specific computing platform, typically abbreviated JVM);
and the Java platform, a JVM running compiled Java
bytecodes, usually calling on a set of standard libraries
such as those provided by Java Standard Edition (SE) or
Enterprise Edition (EE). Though coupled by design, the
language does not imply the JVM, and vice versa.
