In this tutorial, we will learn about one of the core components of Java i.e the what is Java Runtime Environment . We will cover its basic structure and understand why it is needed in Java. This tutorial will also cover the installation of JRE into your local computer.

What is the Java Runtime Environment (JRE)?

Any software that is executed needs an environment in which it can rest and operate. The primary environment in a computer is its operating system (OS). All the software generally runs on the OS. It is not efficient to always run everything on the OS directly.

Specifically for Java programs, there is a special environment that can run Java programs virtually on an OS, it is called the Java Runtime Environment (JRE). The Java Virtual Machine (JVM) which is the core part of Java responsible for executing Java programs also sits on the JRE.
