Set java environment variables

I have set my java environment variables as described:

under System variables i have the following:

Variable : JAVA_HOME and the values for this as : C:\Program Files\Java\jdk1.7.0_80

and the variable 'path' i have added the same file path as that of JAVA_HOME that is : C:\Program Files\Java\jdk1.7.0_80

but when i check my java version from command prompt it shows: java version 1.8.0_152.

what am in doing wrong. I have both jdk 1.8 and 1.7 installed in my machine. I am working on windows 10 - 64 bit machine

You should set the variable path till bin directory 

JAVA_HOME : C:\Program Files\Java\jdk1.7.0_80
PATH      : %JAVA_HOME%\bin

Explanation

To compile and run a java program we use javac and java commands.But these commands are unknown to your OS until we explicitly specify the location of these executable files. This is the main reason why we need to set path in Java and while specifying the path we specify the path of bin folder which contains the executable files.
