g Using interfaces, you can specify similar behaviors for possibly disparate classes. Governments and companies worldwide are becoming increasingly concerned with carbon footprints (annual releases of carbon dioxide into the atmosphere). Many scientists blame these greenhouse gases for the phenomenon called global warming. Create three small classes unrelated by inheritance such as classes Building, Car and Diet. Give each class some unique appropriate attributes and behaviors that it does not have in common with other classes. Write an interface CarbonFootprint with a getCarbonFootprint method. Have each of your classes implement that interface, so that its getCarbonFootprint method calculates an appropriate carbon footprint for that class. Write an application that creates objects of each of the three classes, places references to those objects in and array, then iterates through the array polymorphically invoking each objects getCarbonFootprint method. For each object, print some identifying information and the objects carbon footprint.
