Let's get more practice with maps! Create a class called UniqueCounter. You should provide two methods:

1. add, which takes an Object and does not return a value
2. get, which takes an Object and which returns an int.

get should return the number of times that add has been called for that Object on that UniqueCounter instance.

For example, which your class is done it should work like this:

We suggest that you use a Map internally to track the number of times you have seen a particular Object value.
