basically we use marker interface to make special type of object.
If we take an example of a book shop where we find different type of books, in that suppose you want to display all the books which are related to Java then you can use marker interface there.
You can create a Interface say JavaBooks which wont be having any methods(A blank interface), then all the classes(say for example I say MyJavaBook) implements this blank Interface.
And then while displaying all the books related to Java you can chk using instancOf whether the book is of type JavaBooks(Marker Interface which we created previously).
