You want to create a new Set
but, because a Set
is abstract, you should use a HashSet
. So, first import
the Hashset
at the top of the class. Then you want to assign a new HashSet
of strings into mTags
- remember, you're calling the constructor so you'll need some parentheses too.
Let me know how you get on.
Steve.
