serialization of Objects

Object serialization is also called persistence of objects, serialization of objects (or crossdress)

When using the serializable interface for serialization, if an attribute in an object does not want to be serialized, it can be declared using the transient keyword.

Static properties that are modified by static cannot be serialized, only the properties of the objects in the heap memory.

Any-access-modifier (arbitrary access modifier) Static final long serialversionuid = 42L;

Statement: Defines a fixed identity for a class, and the new class can manipulate objects that have ever been serialized for convenience of serialization.
