What are the Alternatives to Serialization? If Serialization is not used, is it Possible to Persist or Transfer an object using any other Approach

by

In case, Serialization is not used, Java objects can be serialized by many ways, some of the popular methods are listed below:

  • Saving object state to database, this is most common technique used by most applications. You can use ORM tools (e.g. hibernate) to save the objects in a database and read them from the database.
  • Xml based data transfer is another popular mechanism, and a lot of XML based web services use this mechanism to transfer data over network. Also a lot of tools save XML files to persist data/configurations.
  • JSON Data Transfer – is recently popular data transfer format. A lot of web services are being developed in JSON due to its small footprint and inherent integration with web browser due to JavaScript format.
