yum is the default package manager for distributions that use RPM packages. This section will show you how to install the prebuilt OpenJDK JRE and JDK packages using the yum package manager. With that in mind, try to only install the version of Java that you need to run or develop your application(s). You may install various versions and releases of Java on a single system, but most people only need one installation. Most Java applications will work fine with either but you should use whichever implementation your software calls for. Both implementations are based largely on the same code but OpenJDK, the reference implementation of Java, is fully open source while Oracle Java contains some proprietary code.

There are also two different implementations of Java: OpenJDK and Oracle Java. The JDK includes the JRE as well as other software that is required for writing, developing, and compiling Java applications and applets. JRE is an implementation of the Java Virtual Machine (JVM), which allows you to run compiled Java applications and applets. There are two different Java SE packages that can be installed: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). Almost all open source Java software is designed to run with Java SE. This tutorial is focused on Java SE (Java Platform, Standard Edition). There are three different editions of the Java Platform: Standard Edition (SE), Enterprise Edition (EE), and Micro Edition (ME). You can learn how to configure a regular user account by following the steps in our initial server setup guide for Rocky Linux 8. Prerequisitesīefore you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server – this is the user that you should log in to your server as.

This tutorial covers installing the latest, default version of Java, as well as cherry-picking any older versions for installation, and switching between multiple versions in your environment as needed.

Java is a popular programming language and software platform that allows you to run many server-side applications.

This tutorial will show you how to install Java on current versions of RPM-based Linux distributions: Red Hat Enterprise Linux, CentOS, Fedora, and Rocky Linux.
