ResponseEntity
ResponseEntity is a concept used in web development, particularly in Java-based applications, to represent the complete HTTP response sent to a client. It includes not only the data (like a website or API response) but also metadata such as status codes (indicating success or errors) and headers (additional information like content type). Think of it as a packaged message from a server that clearly communicates both the content and its context, enabling precise control over what the client receives and how it's delivered.
