Java

Did I sleep through a class on the Java tracks? This video assumes I've been taught about Set previously...

Without digging too deep into the past several dozen bite-sized lecture videos, I'm fairly certain I haven't taken a video explaining the Set functions at all. I have watched a video about Types, Type arguments, Lists, and Maps. I can definitely do my own reading on the Set command but feel like I'm missing a previous video that Craig recorded. Maybe somebody can enlighten me.

Also the possibility that I've completely forgotten a lecture on the track is greater than zero.
