Let’s go and enjoy OpenJDK! Getting OpenJDK I just got my CentOS machine ready, now I need to set OpenJDK. For Linux, I prefer the OpenJDK one as it’s more convenient on the Linux platform and almost all the major Linux distros integrate with OpenJDK easier than the Oracle counterpart.ĬentOS is the open-source and community edition of the well-known and respected RHEL (Red Hat Enterprise Linux). You can work with both the Oracle Java and the OpenJDK. Admittedly, Ive only opened IntelliJ a few times since the change. I havent had nag problems after editing the plist, provided I have opened the app at least once before editing. Linux is my favorite platform for programming, especially Java. I have changed my JDK version to '1.8', now that I have Oracle Java 8 installed. When you wish to run it, it’s the task of the JRE to read the universal binary and run it smoothly on the current system. When you compile a Java program, it generates a “jar” package that contains a universal binary form of the app. Of course, Java programs require a special environment to work on.

Note that by default, JDK comes up with JRE, so you don’t have to manually install JRE again. When it’s necessary to build your apps or do some programming on Java, it’s always important to have all the necessary tools ready, for example, the compiler (also known as JDK – Java Development Kit) and the runtime (also known as JRE – Java Runtime Environment).
