Overview

For this assignment, you will generate a UML class diagram for a class and implement it.

Assignment

House and BuildingCostEstimator classes

Study the following program. It makes use of a BuildingCostEstimator class. You will need to implement the BuildingCostEstimator class so that the program functions properly.

import java.util.Scanner;

/**
 * @author Dr. Chris Taylor
 * @version 2015.10.07
 * 
 * Makes use of the BuildingCostEstimator class to estimate the
 * cost of building a house based on the user's desires.
 */
public class House {

	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		BuildingCostEstimator estimator = new BuildingCostEstimator();
		
		System.out.println("This program will help you estimate the "
				+ "cost of building a house.");

		System.out.println("For your desired house:");
		System.out.print("Enter the total number of square feet: ");
		int sqFeet = in.nextInt();
		estimator.setSquareFeet(sqFeet);

		System.out.print("Enter the number of full bathrooms: ");
		int numFullBaths = in.nextInt();
		estimator.setNumFullBaths(numFullBaths);

		System.out.print("Enter the number of half bathrooms: ");
		int numHalfBaths = in.nextInt();
		estimator.setNumHalfBaths(numHalfBaths);

		System.out.print("Enter the number of bedrooms: ");
		int numBeds = in.nextInt();
		estimator.setNumBedrooms(numBeds);

		System.out.print("Enter the number of windows: ");
		int numWindows = in.nextInt();
		estimator.setNumWindows(numWindows);

		System.out.print("Enter the number of garage spaces (e.g., 2.5): ");
		estimator.setNumGarages(in.nextDouble());
		
		if(estimator.getNumGarages()<2.0) {
			System.out.println("We are in Wisconsin.");
			System.out.println("Perhaps you should reconsider the number of garage stalls.");
			System.out.print("Enter the number of garage spaces (e.g., 2.5): ");
			estimator.setNumGarages(in.nextDouble());
		}

		// Display characteristics and cost of the house
		System.out.print("The cost of building this house with ");
		System.out.printf("%d full baths, %d half baths,\n",
				estimator.getNumFullBaths(),
				estimator.getNumHalfBaths());
		System.out.printf("%d bedrooms, %d windows,\n",
				estimator.getNumBedrooms(),
				estimator.getNumWindows());

		System.out.printf("with a %f car garage and taking ",
				estimator.getNumGarages());

		System.out.printf("up %d square feet\n",
				estimator.getSquareFeet());

		System.out.printf("will take $%.2f to build.",
				estimator.costToBuild());
	}
}

The cost of the home should be based on the following calculation:

• Based cost per square foot of the house: $130
• Add $15,000 for each full bathroom
• Add $7,000 for each half bathroom
• Add $3,000 for each bedroom
• Add $800 for each window
• Add $8,000 for each garage stall

UML Diagram

You must generate a UML class diagram for the BuildingCostEstimator class.
