RestTemplate class method which performs an HTTP HEAD operation.

The correct answer is: A. headforheaders(string, object…)

The headforheaders() method performs an HTTP HEAD operation. It retrieves the response headers for the specified resource without fetching the resource body.

The getforobject() method performs an HTTP GET operation. It retrieves the response body for the specified resource.

The postforlocation() method performs an HTTP POST operation. It creates a new resource at the specified location.

The postforobject() method performs an HTTP POST operation. It creates a new resource and returns the response body.

Here is a code example that shows how to use the headforheaders() method:

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.set("Accept", "application/json");
ResponseEntity<Map<String, Object>> response = restTemplate.headForHeaders("https://example.com/resource", headers);

The response object will contain the response headers for the resource.
