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 Inatallation
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_222 " OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~18.04.1-b10) OpenJDK 64-Bit Server VM (build 25.222-b10, 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.
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
is only available from another source
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
work for me,
sudo apt-get install default-jdk
sudo apt autoremove
sudo apt-get install default-jre
java –version
sudo apt install openjdk-8-jdk
sudo update-alternatives –config java
Existen 2 opciones para la alternativa java (que provee /usr/bin/java).

and my app work.
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.
