When I approach Java problems, I use the collection pattern. However, doing it in Delphi is quite a nightmare since there is no Integer object to handle things.
I need a data structure that holds numbers. I want to be able to add numbers, remove numbers, and check the contents of the collection, and each number must be unique.
I'm not interested in a solution I need to implement and test for bugs myself. Is there a ready object like Java's HashTable?
