Answer with Explanation

Write a Java program to print all the elements of the array.: 


public class Main {
    public static void main(String[] args) {
        int[][] array = {
            {1, 2, 3, 4},
            {5, 6, 7, 8},
            {9, 10, 11, 12}
        };
        
        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                System.out.print(array[i][j] + " ");
            }
            System.out.println();
        }
    }
}
