  1. response.getWriter()

  2. response.getOutputStream()

  3. response.getOutputWriter()

  4. response.getWriter(Writer.OUTPUT_BINARY)

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the difference between writing character data and binary data in a ServletResponse.

Option A) response.getWriter() - This option is incorrect because the getWriter() method retrieves a PrintWriter object that is used for writing character data. It is not used for writing binary data.

Option B) response.getOutputStream() - This option is correct because the getOutputStream() method retrieves a ServletOutputStream object that is used for writing binary data. This is the correct method to use when writing binary data to the ServletResponse.

Option C) response.getOutputWriter() - This option is incorrect because there is no getOutputWriter() method in the ServletResponse interface. This method does not exist.

Option D) response.getWriter(Writer.OUTPUT_BINARY) - This option is incorrect because there is no overloaded getWriter() method that accepts a parameter of type Writer.OUTPUT_BINARY. This method does not exist.

The correct answer is B) response.getOutputStream(). This option is correct because the getOutputStream() method retrieves a ServletOutputStream object that is used for writing binary data to the ServletResponse.
