You can set your JAVA_HOME in /etc/profile. But the preferred location for JAVA_HOME or any system variable is /etc/environment.
Open /etc/environment in any text editor like nano or gedit and add the following line:
JAVA_HOME="/usr/lib/jvm/open-jdk"
(java path could be different)
Use source to load the variables, by running this command:
source /etc/environment
Then check the variable, by running this command:
echo $JAVA_HOME
Update
Usually most linux systems source /etc/environment by default. If your system doesn't do that add the following line to ~/.bashrc
source /etc/environment
After that, run the below command to add the java_home to the path variable.
export PATH="$PATH:$JAVA_HOME/bin"
If you want it permanent, then add the above line to ~/.profile
Now, running $ java -version would return your version.
