Verify the variable was set correctly: echo $JAVA_HOME Reload your system’s environment variables: source /etc/environment

To set the variable for your system: echo 'JAVA_HOME=$(which java)' | sudo tee -a /etc/environment This variable points them to the Java binary file, allowing them to run Java code. Many applications include code or configuration that references the JAVA_HOME environment variable. Note that this is unnecessary if you’ve installed OpenJDK, since it includes the JRE. However, if you only need to run applications that you’ve already downloaded, you can save a bit of disk space by installing the OpenJRE (Java runtime environment): sudo apt-get install openjdk-8-jre
