JDK 8 (often referred to as JDK 1.8) is a full-fledged software development kit that includes everything needed to build, compile, and debug Java applications. Unlike the Java Runtime Environment (JRE), which only executes Java code, the JDK contains critical developer tools:
If you use this JDK today:
Note the default installation path, usually C:\Program Files\Java\jdk1.8.0_161 . JDK 8 fundamentally changed Java with the introduction
: It includes the Java Runtime Environment (JRE) for running Java applications, as well as development tools like the compiler ( javac ) and debugger . Installation Basics To use this file, you typically follow these steps:
If your software requires Java 8 but does not strictly depend on build 161, you should transition to actively maintained alternatives:
