A DESCRIPTION OF THE REQUEST :
Java Lists currently do not have a way of getting the count of a particular object within a List.

JUSTIFICATION :
I ran into this issue when I had a list of objects in which it contained some duplicates, and I needed to know the number of occurrences of specific objects within the list. Basically i built a list of referenced objects from a list of objects and needed the result of how many times a specific referenced object was in this built list, for later use.

I needed something like... myList.elementCount(obj);
where elementCount() returns int number of occurrences or -1 if it does not exist in the list, and obj is the assumed element in the list.

I was able to continue by creating a custom iterator, but the above alternative would have been a quicker solution.
