Name the method defined in the HttpServletResponse class that may be used to set the content type?
-
setResponseContentType
-
setContent
-
setContentType
-
setType
The HttpServletResponse interface has a setContentType(String) method that sets the content type of the response. This method is used to specify the MIME type (like text/html, application/json) and optionally the character encoding. The other options (setResponseContentType, setContent, setType) are not valid methods in HttpServletResponse.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) setResponseContentType - This option is incorrect because there is no method named setResponseContentType in the HttpServletResponse class.
Option B) setContent - This option is incorrect because the setContent method is not used to set the content type in the HttpServletResponse class. It is used to set the actual content of the response.
Option C) setContentType - This option is correct because the setContentType method is used to set the content type in the HttpServletResponse class. It allows you to specify the MIME type of the response, such as "text/html" or "application/json".
Option D) setType - This option is incorrect because there is no method named setType in the HttpServletResponse class.
The correct answer is Option C) setContentType. This option is correct because it is the method defined in the HttpServletResponse class that is used to set the content type.
