I am using Windows 7 and 8 in my PC .
I have installed jdk 7 and created class path for bin as it should be.  But when I enter javac in the command prompt, it throws an error:
 `javac is not recognizing as internal and external`.
I have searched for a solution in many websites but nothing could solve my problem. Would you please help me and suggest where my mistake could be?
