In this article we will learn “Java 17 Installation on Ubuntu 22.04 LTS [5 Steps]”.
Introduction:
Java 17 is a long-term support (LTS) release of the Java programming language and platform. In this step-by-step tutorial, we will guide you through the process of installing Java 17 on Ubuntu 22.04 LTS and configuring the necessary environmental variables for your development environment.
Prerequisites:
Before we start, make sure you have the following prerequisites in place:
- A user account with sudo privileges.
- Access to the internet.
- An up-to-date Ubuntu 22.04 LTS system.
- A text editor (optional).
Let’s start the steps of “Java 17 Installation on Ubuntu 22.04 LTS [5 Steps]”.
Steps of “Java 17 Installation on Ubuntu 22.04 LTS [5 Steps]”:
Step #1:Update Your Ubuntu 22.04 LTS:
Begin by opening a terminal and updating your system’s package list to ensure you have the latest package information:
ubuntu@Rushi-InfoTech:~$ sudo apt-get update
Step #2:Install Java 17 on Ubuntu 22.04 LTS:
As Ubuntu 22.04 LTS may not include Java 17 by default, we will install it using OpenJDK, the open-source Java Development Kit. Run the following command to install Java 17:
ubuntu@Rushi-InfoTech:~$ sudo apt install openjdk-17-jdk
Step #3:Verify Java Installation on Ubuntu 22.04 LTS:
Once the installation is complete, verify that Java 17 has been installed correctly by running the following command:
ubuntu@Rushi-InfoTech:~$ java -version
This command should display information about the installed Java version, confirming that Java 17 is now available on your system.
Step #4:Set Environmental Variables (Optional):
Configuring environmental variables can be beneficial for managing Java versions and ensuring that Java-based applications run smoothly. Here’s how to set the JAVA_HOME variable and update the PATH:
- Open your shell’s configuration file (e.g.,
~/.bashrcfor Bash) using a text editor:
ubuntu@Rushi-InfoTech:~$ nano ~/.bashrc
- Add the following lines to the file, replacing
/usr/lib/jvm/java-17-openjdk-amd64with the actual path to your Java installation directory:
export JAVA_HOME="/usr/lib/jvm/java-17-openjdk-amd64" export PATH="$PATH:$JAVA_HOME/bin"
- Save the file and exit the text editor.
- To apply the changes, either restart your shell session or run:
ubuntu@Rushi-InfoTech:~$ source ~/.bashrc
Step #5:Verify Environmental Variables:
Confirm that the environmental variables are set correctly by running these commands:
ubuntu@Rushi-InfoTech:~$ echo $JAVA_HOME
ubuntu@Rushi-InfoTech:~$ echo $PATH
These commands should display the Java installation directory and include it in the PATH.
Conclusion:
Congratulations! You have successfully installed Java 17 on your Ubuntu 22.04 LTS system and configured the essential environmental variables. You are now equipped to develop and run Java applications with the power of Java 17. Enjoy coding!
