“ ‘javac‘ is not recognized as an internal or external command ,operable program or batch file.”

Whenever we are getting above information then decide in our system java is installed but the java is not working.

Why java is not working Reason:-

C:\Users\ATUL>javac

Whenever we are typing javac command on the command prompt operating system will pickup javac command search for that command,

1. in the internal operating system calls but javac is not available in the internal system calls list.

1. If it not available in internal system calls list then immediately it won’t raise any error, it will search in environmental variables

In above two cases if the javac command is not available then operating system will raise error message “javac is not recognized as an internal or external command”To overcome above problem to make eligible javac command operating system set environmental variables.

The location of javac command is : C:\Program Files\Java\jdk1.7.0\bin

Right click on mycomputer	—>properties—–	>Advanced system setting—>Environment Variables —
User variables  >new   >——-	variable name : path
	Variable value :  C:\programfiles\java\jdk1.6.0_11\bin;
