Avoiding multiple If statements in Java

Question

I\'ve coded a method something like this. But I guess this should undergo refactoring. Can any one suggest the best approach to avoid using this multiple if statements?

Answer 1

Easiest and shortest way for this particular problem would be using the builtin Java SE or EE methods.

Either in "plain vanilla" client application (which derives this information from the underlying platform):

String mimeType = URLConnection.guessContentTypeFromName(filename);

Or in a JSP/Servlet web application (which derives this information from the web.xml files):

String mimeType = getServletContext().getMimeType(filename);
