How to Set Java_Home in Unix
In Unix-based operating systems, including Linux distributions, various paths are stored in variable documents. This makes it so that when you are in the Terminal, you can use a single command instead of entering the full path of that command at any given time. To change the "Java_home," which is the home directory for your Java, you must edit the path profile for your user.
