HttpServletResponse - writing to response writer vs outputstream

Question

When adding to some content to HttpServletResponse in java I can either get the response writer and append:

httpResponse.getWriter().append("Some Content");

Or I can add content to the output-stream:

ServletOutputStream servletOut = httpResponse.getOutputStream();
servletOut.write(someByteArray);

Is the only difference between the two is that the first gets strings/char-sequences and the second gets bytes (of course the content-type is affected as well)? Should I prefer one over the other? When should I use which?

Answer 1

Below table shows difference between them, You can use any of these based on requirement which fits in the table.
