This will include all the relevant versions of Java that are available for installation in official repositories, and the JDK and JRE packages. In this tutorial, we will go over the step by step instructions to install Java on all major Linux distros. Although this is pretty easy to do, the instructions will vary depending on a user’s Linux distribution, what version of Java they wish to use, and whether they need the JDK (Java Development Kit) or just the JRE (Java Runtime Environment). To get started with programming Java, or to simply run Java applications or applets on Linux, you will need to install the appropriate Java software package. Enter the following source code and save as " Hello.java" under the " ~/myProject" directory created earlier.Many developers and programmers choose to use a Linux system as their work environment because of its stability, speed, and ease of use. File Explorer ⇒ Home ⇒ Create a new folder called " myProject" to keep our works.Step 2: Compile and Run a Hello-world Java Program Rerun the configuration file by: // Refresh $ source /etc/profile // Check the new settings for JAVA_HOME and PATH $ echo $JAVA_HOME Open a Terminal and issue these commands:Įxtract the downloaded package (Check your downloaded filename!) $ cd /usr/local/java First, create a directory "java" under "/usr/local". We shall install JDK under "/usr/local/java" (or Ubuntu's default JDK directory /usr/lib/jvm or /opt/java).
