path - Setting up enviromental variables in Windows 10 to use java and javac

Question

I got a new laptop with Windows 10 and I want to set it up so I can use java and javac from the command line.

I have searched online but all the guides are for previous versions, and I don't want to mess around with something I don't understand.

Answer 1

Just set the path variable to JDK bin in environment variables.

Variable Name : PATH 
Variable Value : C:Program FilesJavajdk1.8.0_31in

But the best practice is to set JAVA_HOME and PATH as follow.

Variable Name : JAVA_HOME
Variable Value : C:Program FilesJavajdk1.8.0_31

Variable Name : PATH 
Variable Value : %JAVA_HOME%in
