What is Java serialization and How is Java serialization implemented?

Serialization is a mechanism for dealing with the flow of objects, so-called object flow is the flow of the object's contents. Can
Read-write operations are performed on the convective objects, and the streamed objects can be transferred between the networks. Serialization is to solve
The problem that is raised when reading and writing to an object stream.
Serialization implementation: Implements the Serializable interface for the class that needs to be serialized, which does not have to be implemented
method, implementsserializable just to mark that the object can be serialized, and then use an output stream (such as:
FileOutputStream) to construct a ObjectOutputStream (object flow) object, and then use the
The WriteObject (Objectobj) method of the ObjectOutputStream object writes out the object with the parameter obj (that is, the
State), the input stream is used to restore
