What is POJO and POJO Class?
POJO -- Plain Old Java Object

Definition of POJO:
   - A simple Java class that encapsulates fields, provides setters and getters,
   and follows basic Java conventions.
   - Contains only data, without business logic or framework-specific
   annotations.
Characteristics:
   - No external dependencies or framework annotations.
   - Facilitates clear representation of data structures.

POJO Class:

Definition of POJO Class:
   - A Java class that adheres to the principles of POJO.
   - Typically used to represent data structures in a simple and
   readable manner.
Characteristics:
   - Consists of private fields with corresponding getter and setter
   methods.
   - Encourages encapsulation and modularity.

Use in Rest-Assured:

Request Payload:
   - In Rest-Assured, POJOs are often used to model request payloads for
   POST or PUT requests.
   - Simplifies the construction of JSON or XML request bodies.
Response Payload:
   - POJOs aid in the deserialization of API responses.
   - Allows easy conversion of JSON/XML response bodies into JAVA objects
   for manipulation.
