RESTful APIs form the communication backbone of modern web applications. GeeksforGeeks provides comprehensive tutorials on creating REST APIs using Java Spring Boot, which allows developers to build scalable and production-ready web services with minimal configuration. GeeksForGeeks - JAVA Backend Development

Java backend development focuses on building secure, scalable server-side logic, leveraging the "Write Once, Run Anywhere" capability of the Java Virtual Machine (JVM). Modern Java development relies heavily on the Spring ecosystem—including Spring Boot for configuration, MVC for RESTful APIs, and Data JPA for database interactions—to streamline the creation of enterprise-level applications.
