JDK vs JRE

Java Runtime Environment (JRE) is a piece of software installed on your computer that allows you to run applications developed in Java on your device. It provides certain libraries and other components required to run a Java program.

JRE also includes Java Virtual Machine (JVM), which is an engine also required to run Java applications on a machine. This engine is included in the JRE package and cannot be installed separately.

The Java Development Kit (JDK) is a development kit meant for developers, for developing applications in Java. It includes both the JRE and the JVM. If you are looking to create your own Java applets, then JDK is what you need. If you have JDK already installed on your device, you are not required to install JRE separately, unless a different version is required.

This should clear up if you want to install JRE or the JDK.
