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.

Enter wall height (feet): 12 Enter wall width (feet): 15 Wall area: 180.0 square feet

(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.

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

(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.

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)
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;
