Serializable Interface in Java - The Serializable interface provides the facility to serialize an object. It does not define any methods and member variables. When a class implements serializable interface it simply indicates this class and its sub-classes can be serialized. The serializable interface serves to achieve the Serializ

Serialization in Java is a mechanism of writing the state of an object into a byte-stream. It is mainly used in Hibernate, RMI, JPA, EJB, and JMS technologies.
