JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object). When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization and static data member. 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.
