Scanner in = new Scanner(System.in);
int rows = scan.nextInt();
int cols = scan.nextInt();

char arr[][] = new char[rows][cols]; // 2D char array
        for (int i = 0; i < rows; i++) {
            String data = "";
            if (in.hasNext()) { // input from user 
                data = in.next();
            } else {
                break;
            }
            for (int j = 0; j < cols; j++)
                arr[i][j] = data.charAt(j); 
        }
// to get a 2D char array
System.out.println(Arrays.deepToString(arr));
