There are two standard types of installation available are JDK and JRE. JDK (Java Development Kit) provides the ability to develop a new Java application, which includes Java compiler. JRE (Java Runtime Environment) provides the runtime environment for any Java application with applets. The Java developers required to install JDK and JRE both on their system to create new Java Applications.

Use this tutorial to install OpenJDK Java 8 on Ubuntu 19.10, 18.04 LTS, 16.04 LTS, LinuxMint 19, 18 using PPA. Follow the below steps to install Java 8 on Ubuntu via the command line.
Step 1 – Install Java 8 on Ubuntu
The OpenJDK 8 is available under default Apt repositories. You can simply install Java 8 on an Ubuntu system using the following commands.
Run below commands to install Java 8 on Ubuntu and LinuxMint.
sudo apt update sudo apt install openjdk-8-jdk openjdk-8-jre
Step 2 – Verify Java Installation
You have successfully installed Java 8 on your system. Let’s verify the installed and current active version using the following command.
java -version openjdk version " 1.8.0_252 " OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1ubuntu1-b09) OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)
Step 3 – Setup JAVA_HOME and JRE_HOME Variable
As you have installed Java on your Linux system, You must have to set JAVA_HOME and JRE_HOME environment variables, which is used by many of the Java applications to find Java libraries during runtime. You can set these variables in /etc/environment file using the following command.
cat >> /etc/environment <<EOL JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre EOL
All done, you have successfully installed Java 8 on a Linux system. You may also need to install Tomcat server to run your Java web application. Use our another tutorial to Install Tomcat 7 or Install Tomcat 8 or Install Tomcat 9 on Ubuntu, Debian, and LinuxMint systems.
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
How to upgrade or how to remove java-8 version and install java7 how to set environment variable, can anyone help me with my question?
Hi, I’m getting ‘permission denied’ as an error:
(base) [email protected]:~$ java -version
openjdk version “1.8.0_252”

bash: /etc/environment: Permission denied
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.
Try: sudo nano /etc/environment (or use any other text editor)
Then add the lines:
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
There is a space after equal sign at this line:
JAVA_HOME= /usr/lib/jvm/java-8-openjdk-amd64
This must not be there. 🙂
Thanks Levent, Article has been updated.
thanks!
Thanks for the quick and clear guide.
Interesting stuff! Keep the site up you have a lot of good content! You just helped me and I believe you helped a lot more people
Good write-up. I certainly love this website. Thanks!
Thanks it worked for me
Step 2 still says “Oracle Java 8”
Hi Hugo, Thanks for pointing it. I have updated the tutorial correctly.
This is not an Oracle JDK installation as the title suggest!
I have corrected the title. Earlier this tutorial was for the Oracle Java installation, But as of now, Oracle Java 8 is not available directly, So we change it to OpenJDK.
This works perfectly as of 31-Oct-2019
Working perfectly
Hi, I’m using Ubuntu 18.04 and I’m getting below error :
Package oracle-java8-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

E: Package ‘oracle-java8-installer’ has no installation candidate
This article is out of date, and, as of September 2019, no longer works.
very easy steps. Thanks

worked on LinuxMint. Thanks
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!
Hi,
Java 8 is no more available to download from Oracle site. But if you have any existing installation on another system, can be used to install to your system.
This is not working. It is showing this error E: Package ‘oracle-java8-installer’ has no installation candidate
because oracle changed license for it’s jdk. this tutor is useless and, in fact, scam.
Hi
when i try to intall the java8. By these commands
sudo add-apt-repository ppa:webupd8team/java
sudo apt update; sudo apt install oracle-java8-installer
after the second command i am getting error like this
“Package oracle-java8-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source”
what to do ? and i have tried everything to come out of this i can’t able to do this
plzz help me out.
Unfortunately don’t work anymore 🙁

Java version “1.8.0_40”
Java™ SE Runtime Environment (build 1.8.0_40-b25)
Java HotSpot™ 64-Bit Server VM (build 25.40-b25, mixed mode)
How do I do it for Ubuntu 18.10
Linux Mint 19.1, couldn’t do the last step as the guide says. Ended up doing:
sudo nano /etc/environment
Paste in:
JAVA_HOME=/usr/lib/jvm/java-8-oracle
JRE_HOME=/usr/lib/jvm/java-8-oracle/jre
Save and exit.
Thank you for the guide!
Same here.

i’m not being able to edit the etc/environment file!!!
please help?!
Hello:
You you either open ‘Files’ or ‘nautilus’ with root privileges, you will be able to open the etc/environment file, edit it and save afterward.
the easiest way is to do it through the terminal using sudo for root access (which enables you to edit sensitive files)
$ sudo gedit /etc/environment
add the lines
then save.
done.
This seems to install JRE _not_ JDK as the title of the article states.
Several people have pointed this out in the comments yet these queries remain unanswered.
Perhaps the title of the article is incorrect…
Hi Tim,
This installs JDK and JRE both. After installation you can check install java compiler.
$ javac -version
javac 1.8.0_111
Thank you! This works Great! I was also able to integrate Apache Solr on my website
I am thinking about keeping this up and going on my vps server
Hello, i f i understand this will install JDK too. But i cant find my JDK directory.
any help or explanation ? thank you in advance
I didn’t get a JDK downloaded either. Does anyone have a suggestion ?
I don’t like it.. It’s too easy.
Do you have a harder example?
This is simple and extremely easy explanation

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.
Thank you very much
It is not working for me.
Hi,
What issue are you facing ?
Thanks man. It works perfectly.

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)
Thanks a lot!
Nice article. So the reference in my blog yes
Thanks a lot
thanks
Thanks for that short advice, for now everything is working 😉 and let it stay in this way 😉
Thank you!

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

thank you, greetings from México.
You made my day,, thanks allot
Hi,
I could install java 8 as you wrote, but I still can not set java 8 as a default JRE. And when I would like to add it to the installed JREs I cant find it. Where should it be?
Thank you!
thanks for post !! it was very helpful for me !
Thanks for the guide.. worked fine for me
Thank you very much. This is really helpful.
Awesome! very helpful!
Very useful. Thank you.
Very Easy for install Java in Ubuntu 🙂
Nice Job
great! i always wonder why we haven’t something like a repo to install jdk!
great work
Thanks a lot. Quick, easy and it installs both JDK and JRE version 8!
Wonderful and helpful.
A written tutorial on how to install using the already downloaded tar.gz file will be helpful too. Thanks
This installs the JRE not the JDK/SDK. Is not the same ….
Nice tutorial!
But now, How do you uninstall it?
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.
