When Ubuntu 18.04 LTS was released, I decided to install it on my lab computer running VMware Workstation Pro for testing purposes… the steps below is how I got OpenJdk installed…
If you’re going to be developing any Java programs you probably need Java JRE runtime software installed… There’s the original proprietary Java JRE and JDK from Oracle and an open source version called OpenJRE/JDK…
The open source Java is as good as the proprietary version from Oracle and easier to install and manage on Ubuntu..
This brief tutorial is going to show students and new users how to easily install the open source version of Java JRE on Ubuntu 18.04 LTS. In the past, one could easily install Oracle Java by simply enabling Ubuntu Partner’s repository and using apt-get command. Not anymore.
Now there’s an open source alternative to Oracle JAVA that can easily be installed via simple apt-get command and is as much compatible to probably all Java based applications.
This post is not about installing Oracle Java, but its alternative called Open Java JDK/JRE. Oracle Java isn’t the default anymore, now Open Java JDK/JRE is.
To install OpenJava on Ubuntu, continue with the steps below:
Step 1: Update Ubuntu
First run the update commands to update Ubuntu. To do that, run the commands below:
sudo apt-get update
After running the commands above, Ubuntu should prompt you to update any package that needs to be updated.
Step 2: Check if Java is Installed
After running Ubuntu update commands, run the commands below to check if any Java is installed on the system. To check if Java is installed on your systems, run the commands below.
java --version
If Java is not installed on the systems, you should see the lines below notifying you that Java is not installed, but then suggesting Java packages and how to install them. Now all you have to do is select the package from the list you want and run the apt-get command.
For this post, we want to install Java JDK/JRE so the obvious choice is default-jre
Step 3: Installing Java JDK/JRE
Now that you know the package to install, run the commands below to install Java JDK/JRE on Ubuntu.
sudo apt-get install default-jre
Accept the list of required packages that will also be installed by typing y for Yes. Doing that will install Open Java JDK/JRE on Ubuntu.
Now when you run the command to check whether Java is installed, you should get the results below.
And this is how to install Open Java JDK/JRE on Ubuntu.
Summary:
This post shows students and new users an easy way to Open Java JDK/JRE on Ubuntu systems. It’s an alternative to Oracle Java and the default for Linux and Ubuntu systems. If you’re going to be installing applications that require Java, then follow the steps above to install it.
Enjoy!
