Question

A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor are required. The company charges $18.00 per hour for labor. Create an application that allows the user to enter the number of rooms to be painted and the price of the paint per gallon. The application should use input boxes to ask the user for the square feet of wall space in each room. It should then display the following information:

* The number of gallons of paint required
* The hours of labor required

* The cost of the paint

* The labor charges

* The total cost of the paint job.

Input validation: Do not accept a value less than 1 for the number of rooms. Do not accept a value less than $10.00 for the price of paint. Do not accept a negative value for square footage of wall space.

**** Your program must use a function to compute the total cost of the paint job. ****

Explanation / Answer

import java.util.Scanner; import java.text.DecimalFormat; public class PaintJobEstimator { public static void main(String[] args) { Scanner input = new Scanner(System.in); int numberOfRooms; double pricePerGallon; System.out.println("Enter the number of rooms?"); numberOfRooms = input.nextInt(); System.out.println("Enter the price of paint per gallon"); pricePerGallon = input.nextDouble(); int roomCount = 1; double totalWallSpace = 0; while (roomCount <= numberOfRooms) { System.out.println("Room No." + roomCount); System.out.println("Enter wall Space"); double wallSpaceForRoom = input.nextInt(); roomCount += 1; totalWallSpace += wallSpaceForRoom; } double paintGallonsRequired = gallonsOfPaint(totalWallSpace); double laborHoursRequired = hoursOfLaborRequired(totalWallSpace); double laborCost = laborCharges(laborHoursRequired); double paintCost = costOfPaint(paintGallonsRequired, pricePerGallon); totalCostOfPaintJob(laborCost, paintCost, totalWallSpace); } public static double gallonsOfPaint(double wallSpace) { double paintGallons = wallSpace/115; return paintGallons; } public static double hoursOfLaborRequired(double wallSpace) { double laborHours = (wallSpace/115) * 8; return laborHours; } public static double costOfPaint(double gallons, double price) { double paintCost = gallons * price; return paintCost; } public static double laborCharges(double hours) { double totalLaborCharges = hours * 18; return totalLaborCharges; } public static void totalCostOfPaintJob(double laborCost, double paintCost, double totalWallSpace) { DecimalFormat twoDecimal = new DecimalFormat("#,##0.00"); double totalCost = laborCost + paintCost; System.out.println("Total Wall Space: " + totalWallSpace); System.out.println("Labor cost: $" + twoDecimal.format(laborCost)); System.out.println("Paint cost: $" + twoDecimal.format(paintCost)); System.out.println("The totalcost of the paint job is: $" + twoDecimal.format(totalCost)); } }
