Square

 Objetive

Write a java program that prompts the user to enter a number and a width, and displays a square of that width, using that number for the inner symbol, as shown in this example:

Enter a number: 4
Enter the desired width: 3

444
444
444

 Example Code

// Importing the Scanner class to handle input from the user
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        // Declare variables for the number and width
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter a number: ");
        int number = sc.nextInt(); // Read the number from the user

        System.out.print("Enter the desired width: ");
        int width = sc.nextInt(); // Read the width from the user

        // Loop to display the square with the given width
        for (int i = 0; i < width; i++) {
            // Loop to display the number in each row
            for (int j = 0; j < width; j++) {
                System.out.print(number); // Print the number without a newline
            }
            System.out.println(); // Move to the next line after each row
        }
    }
}
