## Overview

This is a Spring Boot backend with a configured H2 in-memory database and basic REST API. The tree suggests a post-oriented API, plus a separate student API; the sampled entity classes describe users, posts, and bots. The README does not document endpoint behavior, and controller, service, repository, and application source was not sampled, so their wiring and the exact request-to-storage workflow cannot be confirmed. The graph shows the apparent product components without asserting unsupported calls.

Main entry points: [`src/main/java/com/example/demo/controller/PostController.java`](https://github.com/rohitgit20/spring-boot-assignment/blob/main/src/main/java/com/example/demo/controller/PostController.java) (Post controller), [`src/main/java/com/example/demo/com.example.demo/controller/StudentController.java`](https://github.com/rohitgit20/spring-boot-assignment/blob/main/src/main/java/com/example/demo/com.example.demo/controller/StudentController.java) (Student controller)
