Can we create our own Marker Interfaces...?

[Jalli Venkat]

Hi Friends,
I know that " An Interface which doesn't have any methods" is called Marker Interface.
If we create an interface without any methods, is it become a Marker Interface........?
Then what is the main purpose(Need) of Marker Interface..?



Thanks
