POJO  = Plain Old Java Object →

Acronym for Plain Old Java Object.

POJO, or Plain Old Java Object, is a normal Java object class (that is, not a JavaBean, EntityBean etc.)  and does not serve any other special role nor does it implement any special interfaces of any of the Java frameworks. This term was coined by Martin Fowler, Rebbecca Parsons and Josh MacKenzie who believed that by creating the acronym POJO, such objects would have a "fancy name", thereby convincing people that they were worthy of use.

Related slanbg: POJI, short for plain old java interface. It is used to enforce the idea of developing an API against interfaces instead of implementations.

Serialization is the process of converting an object into a stream of bytes in order to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.

Serialization typically means writing the data as a string (think: xml / json) or as raw binary (a byte[] etc). Deserialization is the reverse process; taking the raw data (from a file, from an incoming network socket, etc) and reconstructing the object model. ... That can mean converting it to a byte stream.
