It is a newer addition to java, and it replaces the old school way we did it in the previous tutorial (with the @override and whatnot). My project did not automatically change the way we did it in the tutorial, so I just edited it manually.

In any case an explanation would have been helpful, I too went to the next video and noticed the code was different.
