Press Ctrl + Alt + T to open the terminal and enter the following command mentioned in the box.

sudo apt install openjdk-8-jre-headless

Once you’ve entered that, wait for the system to finish the installation and then move onto step 2.

Set JAVA_HOME Path

All you have to do now is to set the “JAVA_HOME” and “PATH” environment variables and then you are done. Enter the following commands to set your environment variables. Make sure that your environment variables point to a valid installation of JDK on your machine. For Ubuntu 18.04, the path is /usr/lib/jvm/java-8-openjdk-amd64/

export JAVA_HOME=/usr/lib/jvm/java-8-jre-headless

To check whether your JAVA_HOME path has been successfully saved, enter the following command to check.

echo $JAVA_HOME

Add JAVA bin directory to the PATH variable

Like we have added JAVA_HOME path, we will now update the PATH variable as well. To do that, enter the following command on the terminal.

export PATH=$PATH:$JAVA_HOME/bin

This will append the java bin directory to the existing PATH variable. You can also check the PATH variable by entering the following command

echo $PATH
