How to Install Java 8 on Ubuntu and Linux Mint

By RahulFebruary 2, 20242 Mins Read

Optimize your Java development and runtime environment with this comprehensive guide on installing Java Development Kit (JDK) and Java Runtime Environment (JRE) on Linux systems. Java developers need both JDK and JRE to craft and run Java applications and applets efficiently. JDK offers the essential tools for developing Java applications, including the Java compiler, while JRE provides a runtime environment necessary for Java applications.

How to Install Java on Ubuntu and Linux Mint

This guide simplifies the process of installing OpenJDK Java on popular Linux distributions such as Ubuntu and Linux Mint. OpenJDK, an open-source implementation of the Java Platform, Standard Edition, ensures your Java applications run securely and efficiently.

Installation Steps

Update Your Package Index

Begin by updating your package index to ensure you have access to the latest software versions. Execute the following command in your terminal:

sudo apt update

Install Java OpenJDK

Install OpenJDK 8 by running the following command. This command installs both the JDK and JRE, setting up your system for Java development and execution.

sudo apt install openjdk-8-jdk openjdk-8-jre

Verifying the Java Installation

After installing Java, verify the installation to ensure Java is correctly installed on your system. Run the following command to check the installed Java version:

java -version

This command will display the installed OpenJDK version, confirming the successful installation.

Setting Up JAVA_HOME and JRE_HOME Environment Variables

To ensure Java applications can locate the Java libraries, it’s crucial to set the JAVA_HOME and JRE_HOME environment variables. These variables point to the installation directories of JDK and JRE, respectively. You can set these environment variables in the /etc/environment file with the following commands:

cat >> /etc/environment <<EOL
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
EOL

Conclusion

Successfully installing and configuring Java on your Linux system is a foundational step for any Java developer. By following the steps outlined in this guide, developers can efficiently prepare their Linux systems for Java development and application execution. This setup not only facilitates the creation of Java applications but also supports running Java-based software. Whether you’re developing new Java applications or running existing ones, having both JDK and JRE properly installed and configured ensures a robust development and execution environment for your Java projects.

As Benjamin Hecht (and others) pointed out “Permission denied” is raised when trying “cat >> /etc/environment <<EOL ” . Even with “sudo cat >> ” the same applies. To be able to write to /etc/environment this needs to be used:
cat | sudo tee -a /etc/environment <<EOL
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
EOL

Any help would be greatly appreciated! Thanks! Trying to use java for loading a jnlp file so using Java 8 on 18.04.4 appears to be the only way.

It’s not working and it won’t work. You need to update your article. Oracle has made it mandatory to create an account and download the required version. The PPA method is deprecated and it won’t work.
TIP: Make sure you download the binary version or the Oracle 8 JDK.

Actually it is possible to install Java 8 u 131 to Mint 19+ or Ubuntu 18+.
Search for these files on the Internet:
oracle-java8-installer_8u131-1_webupd8_2_all.deb
oracle-java8-set-default_8u131-1_webupd8_2_all.deb
oracle-java8-unlimited-jce-policy_8u131-1_webupd8_2_all.deb
Then:
sudo oracle-java8-installer_8u131-1_webupd8_2_all.deb
sudo oracle-java8-set-default_8u131-1_webupd8_2_all.deb
(and you can install the unlimited one, but not necessary by defalut)
In contrary to the abandoned PPA, you can install these without problems and the ‘Oracle Java 8 Plugin Control Panel’ will work too.
If the .jnlp files don’t open in Firefox, then select “open with” and enter “javaws” .
There is virtually no info of Java 8 for the latest Mint/Ubutu installation over the internet and I had to figure it out too.
I hope it helps!

JRE_HOME=/usr/lib/jvm/java-8-oracle/jre
Save and exit.

  Encountered the same issue – i had to modify the timeout settings in /var/lib/dpkg/info/oracle-java8-installer.postinst to make it run. Sadly, the installer script doesn’t use the system-wide /etc/wgetrc but creates its own wgetrc each time it runs. So, you’ll have to search for the line “echo “timeout = 15″ >> wgetrc” in the postinst file i’ve mentioned above. Now, just set a longer timeout or remove the line completely.

Sure wish this wasn’t the first item coming up in a google search of “installing java 8 jdk on ubuntu” because this isn’t the jdk!

  I agree with you comment !!! It’s not a JDK and only a Runtime then, no option to compile (no javac compiler)

Hi Rahul,

    EDIT: Maybe a helpful hint, I did a…
    java -version
    …this shows me…
    java version “1.9.0-ea”
    Java(TM) SE Runtime Environment (build 1.9.0-ea-b70)
    Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b70, mixed mode)
    So the error messages seem to come from an older installation, that I have to remove. But how?

Hi,
I would like to thank you for helping the non techs like myself first. Could you help me with a problem I get? I am using LM 17.1 and trying to do the installation I get the Binary Code License Agreement display at mt terminal window. There is no way to click ok or accept those terms, failing which the installation aborts. Can you tell me a way around, or what am I doing wrong?
Thanks
Amit

Reply

  Packages can be removed with
  >sudo apt-get –purge remove packageName
  apt-get remove may some times leave behind some files.
  –purge will remove all files.
