If you’re a Linux user looking to get started with Java development, or you just need to install Java to run certain applications, this guide will provide you the necessary steps for successful Java installation on your Linux machine. We’ll be using OpenJDK, an open-source implementation of the Java Platform, Standard Edition.
Step 1: Update Your System
Before you begin, it’s a good practice to make sure all your system’s packages are up-to-date. Open the terminal and run the following command:
sudo apt-get update
Step 2: Check If Java is Already Installed
Java may have been pre-installed on your Linux machine. Confirm this by running the following command in your terminal:
java -version
If you see a Java version output, then Java is already installed. If not, proceed to the next step.
Step 3: Install Java
Installing Java (Open JDK) on Linux is straightforward. You just need to run a single command line in your terminal:
sudo apt-get install openjdk-11-jdk
The system will ask for your permission to continue with the installation. Press Y and then Enter to proceed.
Step 4: Confirm Successful Installation
Once the installation process is done, confirm that Java was installed correctly by checking the version again:
java -version
If the installation was successful, you should see the Java version in your terminal.
Conclusion
That’s it! You have successfully installed Java on your Linux machine. Now you can proceed to develop Java applications or use apps that require Java. Remember, when it comes to installing packages on Linux, it’s always a good idea to keep your system updated and check for pre-existing installations before proceeding.
