Question

This program has five (5) errors in it that require you to debug it. As you find an error, be sure to document what you changed using in-code commenting. . Below is an explanation of how the program should work.

(1) Prompt the user to input a wall's height and width. Calculate and output the wall's area. (Submit for 2 points).

(2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall. Assume a gallon of paint covers 350 square feet. Store this value using a const double variable. (Submit for 1 points, so 3 points total).

(3) Extend to also calculate and output the number of 1 gallon cans needed to paint the wall. Hint: Use a math function to round up to the nearest gallon. (Submit for 2 points, so 5 points total).

Here is the code below

import java.util.Scanner;
import java.lang.Math;

public class PaintEstimator {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
double wallHeight = 0.0;
double wallWidth = 0.0;
double wallArea = 0.0;
double gallonsPaintNeeded = 0.0;
int cansNeeded = 0;
  
final double squareFeetPerGallons = 350.0;
final double gallonsPerCan = 1.0;
  
System.out.println("Enter wall height (feet): ");
wallHeight = scnr.nextDouble();
// Prompt user to input wall's width
System.out.println("Enter wall width (feet): ");
wallHeight = scnr.nextDouble();
// Calculate and output wall area
wallArea = wallHeight * wallWidth;
System.out.println("Wall area: square feet");
// Calculate and output the amount of paint in gallons needed to paint the wall
gallonsPaintNeeded = wallArea/squareFeetPerGallons;
System.out.println("Paint needed: " + gallonspaintneeded + " gallons");
// Calculate and output the number of 1 gallon cans needed to paint the wall, rounded up to nearest integer
cansNeeded = gallonsPaintNeeded / gallonsPerCan; //Hint: this line is missing two operations
System.out.println("Cans needed: " + cansNeeded + " can(s)");

return;
}
}

Explanation / Answer

PaintNeeded.java

import java.util.Scanner;

public class PaintNeeded {

   public static void main(String[] args) {
      
       //Scanner class object is used to read the inputs entered by the user
               Scanner scnr=new Scanner(System.in);
              
               //Declaring variables
               double height,width,area,paint_needed;
              
              
               //Declaring constant
               final double>               
              
               //Getting the height entered by the user
               System.out.print("Enter wall height (feet):");
               height=scnr.nextDouble();
              
              
               //Getting the width entered by the user
               System.out.print("Enter wall width (feet):");
               width=scnr.nextDouble();
              
              
               //calculating the area of the wall
               area=width*height;
              
              
               //1.Displaying the area of the wall
               System.out.println("Wall area: "+area+" square feet");
              
              
               //calculating the paint need to paint the area of the wall (In gallons)
               paint_needed=area/one_gallon_covers;
              
              
               //2.Displaying the no of gallons of paint needed to paint the wall
               System.out.println("Paint needed: "+paint_needed+" gallons");
              
              
               //3.Rounding the required gallons of paint to paint the wall
               System.out.println("Cans needed: "+Math.round(paint_needed)+" can(s)");
      

   }

}

__________________________

output:

Enter wall height (feet):12
Enter wall width (feet):15
Wall area: 180.0 square feet
Paint needed: 0.5142857142857142 gallons
Cans needed: 1 can(s)
