3. Print a 10x10 grid of dashes

Write a Java program to print the following grid.

Sample Solution:

Java Code:

// Define a class named Main.
public class Main {
    // The main method where the program execution starts.
    public static void main(String[] args) {   
        // Declare a two-dimensional integer array 'a' with dimensions 10x10.
        int[][] a = new int[10][10];    
        
        // Use nested loops to iterate over each row and column of the array.
        for (int i = 0; i < 10; i++) {
            for (int j = 0; j < 10; j++) {
                // Print each element of the array, ensuring a minimum width of 2 characters.
                System.out.printf("%2d ", a[i][j]);
            }
            // Move to the next line to represent a new row in the output.
            System.out.println();
        }
    }
}

Sample Output:

 0  0  0  0  0  0  0  0  0  0 
 0  0  0  0  0  0  0  0  0  0 
 0  0  0  0  0  0  0  0  0  0 
 0  0  0  0  0  0  0  0  0  0 
 0  0  0  0  0  0  0  0  0  0 
 0  0  0  0  0  0  0  0  0  0 
 0  0  0  0  0  0  0  0  0  0
