What are Serialization and De-serialization in Java?

Serialization is a process by which you can save or transfer the state of an object by converting it to a byte stream.

During Serialization, the Object is converted into a binary format, which can be persisted into a disk or sent over the network to any other running Java virtual machine. During deserialization, the reverse process is performed by creating an object from a binary stream.

FYI, the serialization process is platform-independent, which means an object serialized on one platform can be deserialized on a different platform.
