What is the serializable interface and what makes an object serializable?

Serializable interface is the interface that acts as the maker persisting without any specific method and members in Java. The maker has the objective of identification of class for serialization method. This helps in the conversion of the object value in the byte form.

Object is serialized by converting the state into byte version and thus can be returned to object copy . The java.io.Serializable interface is the requirement for the conversion of any object of particular class or superclass. This technique is followed for making the data flow on the network efficient and easy.
