Answer / sandeep
An interface that contains no methods. Eg: Serializable,
Cloneable, SingleThreadModel etc. It is used to just mark
java classes that support certain capability.

Answer / ganesh reddy
markble interface does not contains any methods,but
implementing of these interfaces will be recognise by Jvm
then it will decide that "this class is going do
something".for example for cloneable interface implements
by some class x which consists of a,b variable ,But I need
to interchange instance variables a to b and b to a (pass
by value)of class x and i want again the same values for a
and b.At this situations we can implement cloneable
interface.Like this markble interface are very useful as my
knowledge........

href="http://www.javaexperience.com/java-marker-interfaces/">Marker
interfaces in Java</a> are used for marking a specific
behavior and we can only simulate the behavior by writing
custom interfaces without any methods and having
implementing them by other classes.
