Dispenser candy = new Dispenser(100, 50);

declares candy to be a reference variable of the Dispenser type and instantiates the object candy to hold the candies. The number of items in the object candy is 100, and the cost of a candy is 50 cents.

Create the other objects, such as labels and buttons, as previously described.
