Question
Write in java with comments ( CarbonFootprint Interface: Polymorphism) Using interfaces, as you learned in
this chapter, 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) from
buildings burning various types of fuels for heat, vehicles burning fuels for power, and
the like. Many scientists blame these greenhouse gases for the phenomenon called
global warming.
Create three small classes unrelated by inheritance—classes Building, Car and Bicycle.
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 (check out a few websites that explain
how to calculate carbon footprints).
Write an application that creates objects of each of the three classes, places references
to those objects inArrayList<CarbonFootprint>, then iterates through theArrayList,
polymorphically invoking each object’s getCarbonFootprint method. For each object,
print some identifying information and the object’s carbon footprint.
Explanation / Answer
Hi Dear,
Question is too long.
I have implemented all required classes.
//CarbonFootprint.java:
//Declare the interface CarbonFootprint.
public interface CarbonFootprint
{
//Declare a method getCarbonFootprint() to calculate
//the carbon foot print of car, bicycle, and building.
double getCarbonFootprint();
//Declare the method dispDetailsOfObject() to display
//the details of a object of a class to calculate the
//carbon footprints.
void dispDetailsOfObject();
}
//ApplicationCarbonFootprints.java:
//Import the required package.
import java.util.ArrayList;
//Define the class ApplicationCarbonFootPrints.
public class ApplicationCarbonFootPrints
{
//Start the execution of the main() method.
public static void main( String[] args )
{
//Create three objects of three classes Building,
//Car, and Bicycle.
Building bd = new Building(4000);
Car ca = new Car(1000, 30);
Bicycle bi = new Bicycle(6000.00);
//Create an array list containing carbon foot
//prints of the objects of three classes
//Building, Car, and Bicycle.
ArrayList<CarbonFootprint> carbonfoot = new
ArrayList<CarbonFootprint>();
//Place the reference of the object of the class
//Building to the array list.
carbonfoot.add(bd);
//Place the reference of the object of the class
//Car to the array list.
carbonfoot.add(ca);
//Place the reference of the object of the class
//Bicycle to the array list.
carbonfoot.add(bi);
//Start a for each loop over the array list to
//display the carbon foot prints of Building,
//Car, and Bicycle.
for(CarbonFootprint dispPrint : carbonfoot)
{
dispPrint.dispDetailsOfObject();
System.out.print("The total carbon foot ");
System.out.print("print emmision is: " +
dispPrint.getCarbonFootprint());
System.out.println(" pounds per year");
System.out.println("");
}
}
}
