If you don't know what it is then why do you want to write one and how do you plan on using it?

Yeah most people don't know how to google. This is nothing Java specific so you can put the question into context for Google by adding the word "programming" in front of it. So Google: programming marker interface.

And then I guess it is this first hit:

Marker interface pattern - Wikipedia, the free encyclopedia

Like that.marker interface is providing some run time functionality to jvm,how it is providing internally?with our marker interface we can provide runtime functionality to jvm?

according to as i know marker interface means it does't contain any methods,but it providing some run time functionality to objects by jvm like who r implementing that interface.for example "Serializable"interface.for our interface also we can provide that type of functionality?if yes,how it?then i want to know internal implementation.
