where is serialization and deserialization used code example

Example 1: serialization vs deserialization

DE-SERIALIZATION:  JSON --> JAVA OBJECT
SERIALIZATION: 	   JSON <-- JAVA OBJECT

I add jacksonDataBinder dependency in my pom.xml file -> 
it is a json parser. That is used for converting
from java object to json and from json to java object.

Example 2: Serialization and Deserialization

Serialization; when we MAP a Java object to API JSON
format (CONVERT JAVA OBJECT TO JSON);

Deserialization; API JSON/XML ^ MAP it to Java Object
(JSON TO JAVA OBJECT)
