Above you should see a .java file: RecursionDemo. You are to create GUI for this program. It must allow user input and program output. Design your GUI to follow the functionality of the the original programs. In other words, familiarize yourself with how each of the programs work before attempting your GUI version. This time try to make your GUI user friendly. Tell the user what they must do and what outcome to expect.
Add comments to code please.
import java.util.Scanner; public class RecursionDemo { public static void main(String[] args) { System.out.println("Enter an integer:"); Scanner keyboard = new Scanner(System.in);; int number = keyboard.nextInt( ); System.out.println("The digits in that number are:"); displayAsWords(number); System.out.println( ); System.out.println("If you add ten to that number, "); System.out.println("the digits in the new number are:"); number = number + 10; displayAsWords(number); System.out.println( ); } /** Precondition: number >= 0 Displays the digits in number as words. */ public static void displayAsWords(int number) { if (number < 10) System.out.print(getWordFromDigit(number) + " "); else //number has two or more digits { displayAsWords(number / 10); System.out.print(getWordFromDigit(number % 10) + " "); } } /** Precondition: 0 <= digit <= 9 Returns the word for the argument digit. */ private static String getWordFromDigit(int digit) { String result = null; switch (digit) { case 0: result = "zero"; break; case 1: result = "one"; break; case 2: result = "two"; break; case 3: result = "three"; break; case 4: result = "four"; break; case 5: result = "five"; break; case 6: result = "six"; break; case 7: result = "seven"; break; case 8: result = "eight"; break; case 9: result = "nine"; break; default: System.out.println("Fatal Error."); System.exit(0); break; } return result; } }
