Building REST APIs in Java: Are you a beginner to Java?

REST APIs, built using HTTP, allow applications to communicate by exchanging requests and responses. Java is a popular language for building REST APIs due to its robustness and support for frameworks like Spring Boot. To build a REST API in Java, you need Java Development Kit (JDK), an IDE, Maven or Gradle, and Spring Boot. Start by setting up a Spring Boot project, adding necessary dependencies, and creating a simple REST controller using the @RestController annotation. Use @GetMapping to bind HTTP GET requests to endpoints, and @PostMapping to handle POST requests. Create data models for your endpoints, such as a User class. Implement methods in your controller to return data or handle user input. Test your API using tools like Postman or curl. Explore advanced topics like data validation, database integration, and error handling. Connect with the author in the comments section for questions, feedback, or sharing your projects.
