Seriously? Yep, he was serious. I almost walked away right there, but then the donut called out to me: "...
What happens when a duplicate key is put into a HashMap?
...laces the previous value associated with the given key in the map (conceptually like an array indexing operation for primitive types).
The map simply drops its reference to the value. If nothing else holds a reference to the object, that object becomes eligible for garbage collection. Additionall...

Getting the first and last day of a month, using a given DateTime object
...
