Get the extension from a MimeType

Question

I want to get the extension from a MimeType.

For example:

video/mp4                       ---->  mp4
application/x         


        

Answer 1

There are two ways generally:

• have a mapping of MimeTypes to extensions;
• compute it, using some logic;

The second approach is really not good, so I offer it only for completion. For the first approach you can use this resource: https://www.freeformatter.com/mime-types-list.html

I would use HashMap - the key being the MimeType and the value be the extension (or similar).
