JAVA_HOME is an env variable just like CLASSPATH,PATH and other env variables .
Say you have installed a java application , that needs to use JDK (for example) . There has to be a way for it to know where JDK is installed . It would then use JAVA_HOME to get that path.

It's used to compile (be it from maven, ant or command line) and run java applications.

How do we know if installed application depends on java or not. I rememeber installing many applications on my laptop but never bothered to find if is java application or not and if it is using java_home or not. Please advise.

If you have java installed you can't know. If you don't have java installed then the os will warn you that you need java, so you know.

There will some obvious things , like if the GUI is swing based . But otherwise you'll have to see the readme or config/startup exe files , that wld give you a hint on using resources like JAVA_HOME .
