Lesson - 1 : Serialization - Serialization And Deserialization
Serialization : To serialize an object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. A Java object is serializable if its class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable.
Deserialization : The reverse process of creating object from sequence of bytes is called deserialization. A class must implement Serializable interface present in java.io package in order to serialize its object successfully. Serializable is a marker interface that adds serializable behaviour to the class implementing it.
