int rows = 5, column = 7;
int[][] arr = new int[rows][column]; 
   
   //2D arrays are row major, so always row first

{
	for (int col = 0; col < arr[row].length; col++)
    {
    	arr[row][col] = 5; //Whatever value you want to set them to

Scanner input = new Scanner(System.in);
for (int i = 0; i < row; i++){
	for (int j = 0; j < column; j++){
        array[i][j] = input.nextInt();
