Creating REST APIs in Java typically involves using frameworks like Spring Boot, which simplifies development. Here’s a concise overview within 1500 characters:

1. Set Up Project: Use Spring Initializr or your IDE to create a Spring Boot project with dependencies like spring-boot-starter-web.

2. Create Model Class: Define data models representing your resources.

3. Create Controller: Use @RestController to define API endpoints.

4. Run Application: The embedded Tomcat server runs your API at http://localhost:8080.

5. Handle Data: Connect to a database with JPA/Hibernate or use in-memory data for simplicity.

6. Additional Features: Add exception handling (@ControllerAdvice), validation (@Valid), and security (Spring Security).

Spring Boot automatically converts Java objects to JSON and vice versa, making REST API creation clean and efficient. This approach provides a scalable foundation for building robust web services in Java.
