Javac

Question

I install jdk and add jdk to enviromental variables. But javac cmd doesn't work already, what should I do ?

Answer 1

Do it again
Double check the route and variable name in environment variables
One Java home, other path

Answer 2

Thanks. Solved.
Environment variable needs the folder C:\Program Files\Java\jdk1.8.0_112\bin which a folder has a javac.exe not a root folder.
