Singleton class is a class, it allows jvm to create only one
object.
note:
most of the people think that servlet is a singleton class.
but it is not a singleton class. Actually for each servlet
one object will be created by container.
But suppose if u want to create another object for same
servlet, that servlet allows us to create another object but
the container (server) will not allow to create second object.

When a huge amount of requests coming to servlet, some of
the servers (espcially weblogic)allows to create second
object for same servlet to handle huge amount of requests,
then how can u say servlet is a singleton class.
"The class, itself doesn't allow to create second object "
is called singleton class.

this helps a lot u.....
