cdan not be reffered to this or super
can only access static data
can only call other static methods

Static Method:
a. Access only static type data (static type instance 
variable).
b. Call only static  method ,if non-static then compile 
time error.
c.No need the class object to call the static method.
d.Cant use this and super keyword otherwise compile time 
error.

Static in context of java is something which is executed at
the time when the class is loaded by either bootstrap loader
or another loader into memory.These are basically for
initializations of the variables which wil be used by all
the instance variables.Say we need ot restrict how many
objects whill be created of the class store the no.of
objects created in a static variable and everytime the
object is called thestatic variable is incremented and as
soon as it reaches a limit restrict it by some logic.

The static methods can be called by the object refrence of
the class or the class name, they cannot use instance
variables or instance methods, they are the part of the
class and not instance, the static variables are stored in
registers and remain in the memory as long as the clas in
unloaded.
