Answer / sreedhar a

As per interface definition all the member variables by
default are public static final. There is no difference
between I and j variables. JVM will consider the j variable
as public static final int j=0;
Note: variables declared in interface must be initialized
otherwise program will fail to compile.

Answer / 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.
