JDK (Java Development Kit)

A collection of development tools sometimes required on web servers that host Java-based applications, enabling compilation and runtime functions.

The Java Development Kit, or JDK, is a collection of tools developers use to build and run Java applications. It includes everything needed to compile, test, and deploy Java-based software on servers or local machines. Some web applications rely on the JDK to operate properly, particularly enterprise systems or platforms built in Java. Many hosting providers offer JDK support or preinstall it for convenience. It's the essential toolkit that turns raw Java code into functional programs, quietly powering everything from backend systems to mobile apps and large-scale enterprise applications.
