public static void main(String[] args) { Scanner input = new Scanner(System. in ); char answer = 'n'; int row = 0; char output = 'k'; do { System.out.println("DO YOU WANT TO START Y OR N?"); answer = input.next().charAt(0); System.out.println("enter the number of rows"); while (!input.hasNextInt()) { System.out.println("Not an integer,try again "); input.next(); } row = input.nextInt(); while (row < 5 || row > 21) { System.out.println("ERROR! Valid range 5 - 21. How many chars/last row?"); row = input.nextInt(); } System.out.println("WHAT CHARACTER?"); output = input.next().charAt(0); for (int i = 0; i
