Accurately Estimating Tile Requirements with a Java Program

Accurately Estimating Tile Requirements with a Java Program

---

As civil engineers, one of the most common tasks we encounter is estimating the number of tiles required to cover a given floor space. Whether working on a small residential room or a large commercial area, precise calculations are essential to minimize material wastage and ensure cost-effectiveness. To simplify this process, I have developed a Java program that efficiently calculates the number of tiles needed based on the floor and tile dimensions. In this post, I will walk you through the pseudocode, flowchart, and the Java code implementation for the program.

Problem Overview

The task at hand is simple: Given the dimensions of the floor and the tiles, we need to calculate how many tiles are required to completely cover the floor area.

Inputs:

• Floor length (in meters)
• Floor width (in meters)
• Tile length (in meters)
• Tile width (in meters)

Output:

• The total number of tiles required, rounded up to the nearest whole number.

Pseudocode

The pseudocode is a high-level abstraction that outlines or provides the description of the program's logic. Below is the pseudocode for the tile calculation program:

1. Start
2. Prompt the user to enter the floor length
3. Read the floor length
4. Prompt the user to enter the floor width
5. Read the floor width
6. Prompt the user to enter the tile length
7. Read the tile length
8. Prompt the user to enter the tile width
9. Read the tile width
10. Calculate the floor area: floorArea = floorLength * floorWidth
11. Calculate the tile area: tileArea = tileLength * tileWidth
12. Calculate the number of tiles: numberOfTiles = ceil(floorArea / tileArea)
13. Display the number of tiles required
14. End

A flowchart is a visual representation of the program's logic. Below is a textual version of the flowchart that outlines the sequence of operations:

Java Code Implementation

Below is the Java program that implements the tile calculation logic based on the pseudocode:

import java.util.Scanner;
class TileCalculator{
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter the length of the floor: ");
        double floorLength = scanner.nextDouble();
        System.out.println("Enter the width of the floor: ");
        double floorWidth = scanner.nextDouble();
        System.out.println("Enter the length of the tile: ");
        double tileLength = scanner.nextDouble();
        System.out.println("Enter the width of the tile: ");
        double tileWidth = scanner.nextDouble();
        double floorArea = floorLength * floorWidth;
        double tileArea = tileLength * tileWidth;
        int numberOfTiles  = (int) Math.ceil(floorArea / tileArea);
        System.out.println("Number of tiles required: "+numberOfTiles);
        scanner.close();



    }
}

Example Calculation

Let's consider the following example inputs:

• Floor length: 10 meters
• Floor width: 8 meters
• Tile length: 0.5 meters
• Tile width: 0.5 meters

Using the formulae described:

• Floor area = 10 * 8 = 80 square meters
• Tile area = 0.5 * 0.5 = 0.25 square meters
• Number of tiles = 80 / 0.25 = 320 tiles

Output:

Number of tiles required: 320
