For this exercise, we are going to revisit the Pie superclass that we saw as an example in the last lesson. We have added the Pumpkin class, which takes the number of slices and a boolean to indicate if it is made with canned pumpkin. We also added a getType() method in the Pie class. For this exercise, you need to create either an Array or an ArrayList and add 3 pies to that list, an Apple, a Pumpkin, and a third type using the Pie class.

After adding these to your list, loop through and print out the type using the getType() method in the pie class.
