17,961 PointsNot 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.

mTags = new HashSet<String>();
You might need to import HashSet, like so: import java.util.HashSet;
