To answer this question, you need to understand the different methods available in the HttpServletResonse class for sending response data to the client.
Let's go through each option to understand why it is correct or incorrect:
Option A) HttpServletRequest.getWriter() - This option is incorrect because the getWriter() method is used to obtain a PrintWriter object that can send character text to the client. However, this method belongs to the HttpServletRequest interface, not the HttpServletResponse interface.
Option B) HttpServlerResponse.getCharacterWriter() - This option is incorrect because there is no method called getCharacterWriter() in the HttpServletResponse interface.
Option C) HttpServetRequest.getOutputStream() - This option is incorrect because the getOutputStream() method is used to obtain an OutputStream object that can send binary data to the client. It is not used to send character data.
Option D) HttpServletResonse.getWriter() - This option is correct because the getWriter() method in the HttpServletResponse interface is used to obtain a PrintWriter object that can send character data to the client. This is the correct method for sending response data in the form of character data.
The correct answer is D) HttpServletResonse.getWriter(). This option is correct because it provides the appropriate method for sending response in the form of character data to the client.
