How to set JAVA_HOME environment variable:
1. First, locate where Java is installed:
sudo update-alternatives --config java
2. Once you see all the paths, copy the one of your preferred Java version.
3. Then, open the .bash_profile with any text editor. In this example, we use vim:
vim .bash_profile
4. At the bottom of the file, add a line which specifies the location of JAVA_HOME in the following manner:
JAVA_HOME=”/your/installation/path/”
