markble interface does not contains any methods,but
implementing of these interfaces will be recognise by Jvm
then it will decide that "this class is going do
something".for example for cloneable interface implements
by some class x which consists of a,b variable ,But I need
to interchange instance variables a to b and b to a (pass
by value)of class x and i want again the same values for a
and b.At this situations we can implement cloneable
interface.Like this markble interface are very useful as my
knowledge........
