An example of "finity"

For example, imagine a young boy have a jar filled with candies. The number of candies in the jar is finite because there is a definite, limited amount. The boy can count them, and once he has counted them all, he knows that he has a specific number of candies. In this case, the candies in the jar are finite because they have a clear endpoint, and there are only a certain number of candies in the jar—they are not infinite or limitless. The finity of the candies means there is a limited number of candies in the jar (although the boy may wish he had an infinite amount of candy).
