Why did Java Object become JSON?

 This is an important Spring Boot feature.

Spring Boot uses libraries such as Jackson to convert Java objects into JSON for HTTP responses.

Conceptually:

Java Object

     ↓

   Jackson

     ↓

    JSON

     ↓

HTTP Response

For example:

new Student(101, "Rahul", "Java Full Stack")

becomes:

{

  "id": 101,

  "name": "Rahul",

  "course": "Java Full Stack"

}
