This command tells us that packages java-1.8.0-openjdk-headless and java-11-openjdk-headless both provide the java binary. In order to figure out which RPM packages to install, we can ask the packaging system which ones provide the java binary: Let's consider we have a freshly commissioned Red Hat Enterprise Linux 8 machine and we'd like to use it for running Java applications. If you prefer to watch a short 4 minute demo video, here it is: Yes, with JDK 11 you can directly run Java source files. $ /usr/lib/jvm/java-11-openjdk/bin/java HelloWorld.java $ cat > HelloWorld.java HelloWorld.java < $ sudo yum install java-1.8.0-openjdk-devel To install JDK 8, use: (If you didn't select Make this user administrator during install see this article to enable sudo on RHEL) Through this article, you’ll learn how to install and run simple Java applications on RHEL 8, how to switch between two parallel installed major JDK versions via alternatives and how to select one of the two JDKs on a per-application basis. JDK 8 and JDK 11 refer to Red Hat builds of OpenJDK 8 and OpenJDK 11 respectively.
