Iam having doubt on this, Is it mandatory to give only JAVA_HOME as variable name while setting environment variable for java?. I saw so many articles and videos everywhere same variable name JAVA_HOME. (Even for android also only ANDROID_HOME). What is the problem if we give some other variable name? can any one help on this?

Thanks in advance.

    Well some other variable name might not cause any problems, but it wouldn't do the job of setting the Java home directory! Assuming you mean `JAVA_HOME=/some/dir java ...`, that's not an argument to `java`, that's setting an environment variable. – jonrsharpe Oct 11 '17 at 14:36

You can set some other name but some application that use java try to search for "JAVA_HOME" in order to setup and make itself running , say some IDE that uses java, by default it searches for that environmental variable.

JAVA_HOME is the standard environment variable name for where Java resides on your system. If you change it to be JAVA_HOME_OTHER for example, any Java application relying on JAVA_HOME env variable to bet set will fail to run.
