Given a base Plant class and a derived Flower class, complete main () to create an ArrayList called myGarden. The ArrayList should be able to store objects that belong to the Plant class or the Flower class. Create a method called printArrayList (), that uses the printInfo () methods defined in the respective classes and prints each element in myGarden. The program should read plants or flowers from input (ending with - 1), adding each Plant or Flower to the myGarden ArrayList, and output each element in myGarden using the printInfo () method.
