Solution
First compile all the classes.But to run the program we have to run the class which is having the
main method.
here TestEveryOne.java class is having the main() method.If we run the program we may get the
output.
Before Posting the code I checked for Errors twice,Only After ensuring that this programs are
having no errors and working fine am posting.If Any Problem Happened just do comment.I will
be available until you satisfied with my answer. _Thank you
