Java is a general-purpose programming language that is fast, reliable, secure, popular and widely used. It is an environment to develop and run a wide range of applications, from mobile applications to desktop and web applications and enterprise systems – Java is everywhere!
If you are planning to create a program in Java, then you need to install a JDK (Java Development Kit). If you are planning to execute a Java program, you can do that on a JVM (Java Virtual Machine), which is included in the JRE (Java Runtime Environment). If in confusion, install the JDK because this is frequently needed even if the motive is not to create Java programs.
There are many flavors of Java out there and also many versions of each flavor. In this article, we will show you how to install both OpenJDK and Oracle JDK (Oracle Java SE) in Fedora.
Most Java applications run on one of the following:
- OpenJDK?—?an open-source implementation of the Java Platform, Standard Edition
- Oracle Java SE?—?a free JDK from Oracle
