Classes that require special handling during object serialization and deserialization must implement special methods with exactly the following signatures [API 2006]:
| Code Block |

private void readObjectNoData() throws ObjectStreamException;

Note that these methods must be declared private for any serializable class. Serializable classes may also implement the readResolve() and writeReplace() methods.
According to the Serialization Specification [Sun 2006], readResolve() and writeReplace() method documentation:
