Marshalling is the process of converting a POJO (Plain Old Java Object) in memory into a format that can be written to disk or send via network, usually in text formats like XML or JSON. The reverse of this technique is called unmarshalling.
Marshalling is similar to Serialization in practice but the difference is that, Marshalling also saves the code of an object in addition to its state.
