Question

Java Programming

A program is required to calculate the amount of paint needed for painting a
fence. The program assumes that 1 litre of paint covers 5 m^2 and that the
user is able to input the height and the length of the fence.

Answer 1

import java.util.Scanner;

public class PaintCalculator {
  
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.print("Enter the length of the fence: ");
double length = Double.parseDouble(sc.nextLine().trim());
System.out.print("Enter the height of the fence: ");
double height = Double.parseDouble(sc.nextLine().trim());
  
// calculate the area of the fence
double fenceArea = (length * height);
  
// Paint required for painting 5 m^2 of fence = 1L
double painRequired = (fenceArea / 5);
  
System.out.println("Amount of paint required to paint "
+ String.format("%.2f", fenceArea) + " m^2 of fence = " + String.format("%.2f", painRequired) + " L.\n");
}
}
