Java Java Data Structures Efficiency! Add tags to a course

Not sure what it is asking me to do for add tags to a course

I am being asked to add mTags to the constructor, but I"m not sure what the tag is supposed to be. I tried to add the title to the set, but I think I'm too shaky on how to add to sets.

I rewatched the previous video several times and he creates a Hashmap but not a set of strings.

Try instantiating it as a HashSet!

mTags = new HashSet<String>();

You might need to import HashSet, like so: import java.util.HashSet;
