Answer Posted / ramakrishna
generally if we want to access the variables(non-static)
which are present in the class we use the reference of that
class. we get the reference of the class after creation of
the object. but we can not able to create the object of the
interface if we define the non-static variables inside the
interface if we want to access it is not possible so if we
want to define the variables we should have to define the
variables as static.
