Carpet Calculator:

The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 long by 10 feet wide is 120 square feet. To cover that floor with carpet that costs 8$ per square foot would cost $960. (12 X 10 X 8 = 960.)

First, you should create a class named RoomDimension that has two fields: one for the length of the room and one for the width. The RoomDimension class should have a method that returns the area of the room. (The area of the room is the room\'s length multiplied by the room\'s width.)

Next you should create a RoomCarpet class that has a RoomDimension object as a field. It shoud also have a field for the cost of the carpet per square foot. The RoomCarpet class should have a method that returns the total cost of the carpet.

Once you have written these classes, use them in an application that askes the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet.

Solution

class RoomDimension{
private int length;
private int width;
public RoomDimension(int length,int width){
this.length=length;
this.width=width;
  
}
public int areaOfRoom(){
int area=length*width;
return area;
}

}
class RoomCarpet{

RoomDimension d;
int costpersquarefoot;
public int totalCost(int cost){
int total;
this.costpersquarefoot=cost;
d= new RoomDimension(12,10);
total=d.areaOfRoom()*costpersquarefoot;
return total;
  
}
}

public class Test{
public static void main(String... s){
RoomCarpet r=new RoomCarpet();
  
System.out.println(\"total price for carpeting\"+r.totalCost(960));
}

}
