Question

Create an application using java that prompts the user for a rectangular room's length, width, and height?

Answer 1

To create an application in Java that prompts the user for a rectangular room's length, width, and height, you can use the Scanner class to read input from the user. Then, calculate the volume of the room by multiplying the length, width, and height. Finally, display the calculated volume to the user.

Step-by-step explanation:

In Java, the Scanner class provides a convenient way to receive input from the user. By using this class, you can prompt the user to enter the length, width, and height of a rectangular room. Once these values are obtained, the application can use a simple multiplication operation to calculate the volume of the room. The formula for volume (V) of a rectangular room is given by V = length × width × height. This calculation can be performed using a straightforward Java expression.

Here's a basic example code snippet:

java

import java.util.Scanner;

public class RoomVolumeCalculator {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

System.out.print("Enter the length of the room: ");

double length = scanner.nextDouble();

System.out.print("Enter the width of the room: ");

double width = scanner.nextDouble();

System.out.print("Enter the height of the room: ");

double height = scanner.nextDouble();

double volume = length * width * height;

System.out.println("The volume of the room is: " + volume);

// Close the scanner to avoid resource leaks

scanner.close();

}

}

This code prompts the user for the dimensions, calculates the volume, and then prints the result. It's essential to close the Scanner object to prevent resource leaks after reading user input.
