For the first method, addTag
, it receives a tag
as an argument. Use add
on mTags
using dot notation and pass in the tag
the method received.
The second method receives a List
of strings. For this, create a for
loop to iterate over the list. Inside the method call the first method to add each element of the list to mTags
by passing the loop variable value to addTag()
..
Let me know how you get on.
Steve.
