While knowledge of the standard may no longer be crucial for programmers due to abstraction of this detail it is placed here for completeness and as a reference in case the need arises to parse raw data and the result is not as expected.

Java's Serializable interface provides an easy-to-use programming interface for converting between a runtime object and a byte stream.
Serialization involves mapping a runtime object or an object graph into an ObjectOutputStream, which can then be written to the filesystem or stored in a database. Conversely, deserialization reads the byte stream through the ObjectInputStream and then maps the byte stream into an object or an object graph. During object serialization, the default Java serialization mechanism writes the metadata about the object, which includes the class name, field names and types, and superclass. This class definition is stored as a part of the serialized object.
