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 Oracle Java 8 on Ubuntu 18.04 LTS, 16.04 LTS, 14.04 LTS and LinuxMint 19, 18 using PPA. Follow the below steps to Install Oracle Java 8 on Ubuntu command line.
Step 1 – Install Oracle Java 8 on Ubuntu
You need to enable additional repository to your system to install Java 8 on Ubuntu VPS. After that install Oracle Java 8 on an Ubuntu system using apt-get. This repository contains package named oracle-java8-installer, Which is not an actual Java package. Instead of that, this package contains a script to install Java on Ubuntu.
Run below commands to install Java 8 on Ubuntu and LinuxMint.
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer
Step 2 – Verify Java Inatallation
The apt repository also provides package oracle-java8-set-default to set Java 8 as your default Java version. This package will be installed along with Java installation. To make sure run below command.
sudo apt-get install oracle-java8-set-default
After successfully installing Oracle Java 8 using the above steps, Let’s verify the installed version using the following command.
java -version java version " 1.8.0_171 " Java(TM) SE Runtime Environment (build 1.8.0_171-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
Step 3 – Setup JAVA_HOME and JRE_HOME Variable
After installing Java on Linux system, You must have to set JAVA_HOME and JRE_HOME environment variables. Which is used by many 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-oracle JRE_HOME=/usr/lib/jvm/java-8-oracle/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.

Great information. Appreciate the time you took to share this feedback for us computer nerds. Love your blog too. Java is still one of the best options out there.
step 1 Can do add-apt-repository ppa:webupd8team/java && apt-get update && apt-get install oracle-java8-installer allso little bit easy 🙂
hi,
there is an error with python-samba while installing oracle-java8-installer.

how can i solve this problem?
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.

Hi Ian,

E: The list of sources could not be read.
Very nice, simple and useful
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!

Same here, HARSHITA.
Worse: I can’t install any package since I’ve tried to install this using this tutorial. Can someone help please?

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?
Zoli
Very helpful article.
Very helpful,
Thanks !!!
Very helpful article. Thanks.
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
use arrow keys to move, enter to accept
Thank you!! It works!.
Thanks for the info! very helpful…
Thank you so much, this helped a lot !!!!

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.
