Java

The short version

Java is a programming language used for many business services, Android apps, and other software.

Code that runs through a shared platform

Java programs are commonly compiled into a form that runs on the Java Virtual Machine (JVM). That lets the same program run on different computers with a suitable JVM, although it may still need changes for a particular system.

Organisations use Java for web services, business systems, and other long-lived software. Despite the similar name, JavaScript is a separate language. Knowing which one a team means matters when discussing skills or tools.
