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.

Java (ArrayList) - Plant Information
![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), add each Plant or Flower to the myGarden ArrayList, and output each element in myGarden using the printinfo() method.
Ex. If the input is:
plant Spirea 10
flower Hydrangea 30 false lilac.
flower Rose 6 false white
plant Mint 4
|-1
the output is:
Plant Information:
Plant Information:
Plant Information:
