If load_on_startup is not enabled in web.Xml then the
servlet crates the object that class and sevletConfig object
will be created after constructor will be executed after it
will go to life cycle methods in servlets.i.e means lot of
processing will be done when load-on-startup is not enabled.

If load_on_startup is enabled then that moment when
WEBAPPLICATION is deployed all lot of processing will be done.
Then immediately executes LIFECYCLE method in servlets

Problem: suppose our webapplication contain 10 servlets then
which servlet object will be created?

solution: for this problem If we use load on startup web
container creates the objects based on the proirity when
there are mutliple servlets.We use load_ on_ start up for
giving the proirity.

Note:1 is highest priorty
2 is next highest priorty
-1 ignores that value
EX:<load-on-startup>1</load-on-startup>
