Implement the following endpoints in java, a sample endpoint is provided for guidance: What is an endpoint? When an API interacts with another system, the touchpoints of this communication are considered endpoints. For APIs, an endpoint can include a URL of a server or service. Each endpoint is the location from which APIs can access the resources they need to carry out their function. Following table lists the API endpoints that you are expected to implement. Input column defines the fields that will be sent to the endpoint. Output defines the expected output of the endpoint. Examples regarding the way these are handled are present in the sample code provided Sample endpoint implemented in java: (format for above endpoints is similar)

@RequestMapping(value = "/sample", method = RequestMethod.GET, produces = "application/json") public ResponseEntity helloWorld() { Map response = new HashMap(); try { response.put("message", "Hello World"); response.put("status", true); } catch (Exception ex) { response.put("status", false); } return ResponseEntity.status(HttpStatus.OK).body(response); }
