If u dont keep public in front of class that is not
accessible by third party packages. But if u keep public
infront of class that is accessible by third party
packages.

Problem: class CheckServlet extends HttpServlet
{---- }
Now u want to executed this servlet class in server
(Tomcat,WebSphear,WebLogic) an error will come .Because the
above class is comes under default access modifier.

Ans: public class CheckServlet extends HttpServlet
{-------}
This class services will executed in any server(either
Tomcat,WebLogic etc.,). Because The class is visible in
third party class packages like container packages.
