Answer / namita
Marker Interface or sometimes called as Tagging interface
are empty interface which means it does not have any
methods. The use of the these interface is below
Like clonneable interface which is also a marker interface
when ur code implements clonneable interface the JVM will
come to know that you want to clone the object by calling
clone method(). Similalry serializable interface needs to
be implemented when you want to serialize the objects.
Their implementation is just to make aware the JVM.
