Write a simple Java program code that can be used to capture rectangle dimensions from thekeyboard and then it should compute the area of the rectangle and then display the result on thescreen

Sure, here is a simple Java program that captures rectangle dimensions from the keyboard, computes the area, and displays the result on the screen:

import java.util.Scanner;

public class RectangleArea {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("Enter the length of the rectangle:");
        double length = scanner.nextDouble();

        System.out.println("Enter the width of the rectangle:");
        double width = scanner.nextDouble();

        double area = length * width;

        System.out.println("The area of the rectangle is: " + area);
    }
}

Here's how it works:

1. We import the Scanner class, which is used to get user input.

2. We create a new instance of the Scanner class.

3. We ask the user to enter the length of the rectangle and store the input in the length variable.

4. We ask the user to enter the width of the rectangle and store the input in the width variable.

5. We calculate the area of the rectangle by multiplying the length and width.

6. Finally, we print out the area of the rectangle.
