| Is it possible to create a marker interface by a user ? If possible,
how? If it is not possible, Why?

Is this a question from a test?
Do you know, what a marker interface is? If yes, than the answer to the
question is obvious!
Or do you want to know, what a marker interface is? A marker interface
is an interface that does not contain any methods.
Or do you want to know, how a marker interface is used?
....
Ciao,

| Hi,
I know what is marker interface and how it is usefull.Clonable and
Serializable are the examples for marker interface.
what is the similarities between these two.Is it possible to
define our own marker interface.
Bye,

| Hi,
Although I am still not convinced that this is a test...:

The similarities are that they both do not define any method. Nothing else.

Hmm, do you think, you can define an interface which does not have any
method? If you *really* do not know the answer, try to compile this:
interface MyMarkerInterface {}

Similarities? They are both defective (implied by any
non-composite interface that declares no operations). Yes it is possible
to write your own form of this language defect.
