Question
Please fix this code. It needs to read 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) This is the code: import java.util.Scanner; import java.lang.Math; // Note: Needed for math functions 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; } } Thank you so much!!!
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)
