  • After installing JDK go to the folder where JDK file is stored & copy the destination. The destination would be like “C:\Program Files\Java\jdk1.8.0_111\bin”.

Now if you go to command prompt & type “Javac” it will show as ” ‘Javac’ is not recognized as an internal or external command, operable program or batch file” which means we haven’t set path environment variable.
