String Getrequested ApiVersion

As a software developer, it's not always possible to dive deep into the language you're working with, and sometimes it's difficult to find situations where you need to use advanced or non-trivial features. It's easy to use a magic framework, the hard part is having the necessary knowledge to create it. For this reason, I created the tag #javaunderthehood to gather this content and help other people understand how this magic happens. Feel free to join me with an interesting new topic.
