Solution for Java Program to Calculate Cost of Painting

Problem statement:

A painting company has determined that to paint 115 square feet of wall space, the task will require one gallon of paint and 8 hours of labor. The company charges $20.00 per hour for labor. Design a program that asks the user to enter the number of square feet of wall space to be painted and the price of paint per gallon. The program should then calculate and display the following data:

– Gallons of paint required

– Hours of labor required

– Cost of paint

– Cost of labor

– Total cost

Algorithm:

1. Start the program.

2. Prompt the user to enter the number of square feet of wall space to be painted.

3. Read the input and store it in a variable called “wallSpace”.

4. Prompt the user to enter the price of paint per gallon.

5. Read the input and store it in a variable called “paintPrice”.

6. Calculate the gallons of paint required using the formula: gallons = wallSpace / 115

7. Calculate the hours of labor required using the formula: laborHours = wallSpace / 115 * 8

8. Calculate the cost of paint using the formula: paintCost = gallons * paintPrice

9. Calculate the cost of labor using the formula: laborCost = laborHours * 20

10. Calculate the total cost using the formula: totalCost = paintCost + laborCost

11. Display the calculated data: gallons, laborHours, paintCost, laborCost, totalCost.

12. End the program.

Pseudo-code:

“`

1. Start program

2. Prompt user to enter wall space

3. Read user input and store in variable wallSpace

4. Prompt user to enter paint price per gallon

5. Read user input and store in variable paintPrice

6. Set gallons = wallSpace / 115

7. Set laborHours = wallSpace / 115 * 8

8. Set paintCost = gallons * paintPrice

9. Set laborCost = laborHours * 20

10. Set totalCost = paintCost + laborCost

11. Display gallons

12. Display laborHours

13. Display paintCost

14. Display laborCost

15. Display totalCost

16. End program

Java code:

“`java

import java.util.Scanner;

public class PaintingCompany {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print(“Enter wall space in square feet: “);

double wallSpace = input.nextDouble();

System.out.print(“Enter price of paint per gallon: “);

double paintPrice = input.nextDouble();

double gallons = wallSpace / 115;

double laborHours = wallSpace / 115 * 8;

double paintCost = gallons * paintPrice;

double laborCost = laborHours * 20;

double totalCost = paintCost + laborCost;

System.out.println(“Gallons of paint: ” + gallons);

System.out.println(“Hours of labor: ” + laborHours);

System.out.println(“Paint charges: $” + paintCost);

System.out.println(“Labor charges: $” + laborCost);

System.out.println(“Total Cost: $” + totalCost);

}

}

“`

Explanation:

– The program starts by prompting the user to enter the wall space in square feet and the price of paint per gallon.

– The input values are then used to calculate the gallons of paint required, hours of labor required, cost of paint, cost of labor, and total cost.

– Finally, the calculated data is displayed on the console.

Please note that the formula used to calculate gallons and labor hours assumes that 115 square feet of wall space requires 1 gallon of paint and 8 hours of labor. You can modify these values as per your requirements.
