is the method you use to add a new key-value pair to a Map
object.
add
is the method you use to add a new unique value to a Set
object.
Neither object has the other's method (Map
doesn't have an add
method, Set
doesn't have a set
method). It's just how they are named.

3,467 PointsThe Add method adds a value to the end of the list. Set is used to replace an existing value in a specific index in the list. The usage of either depends on the program you're writing. So just be aware of what each one does and use it accordingly. Hope this helps.
