Question

I need java code...

Background Suppose you're working on the next great cligital assistant to compete with the likes of Siri, Cortana Alexa, and the lameless Google Assistant. An important part of your assistant is a text-10-speerlingine, You've managed to get your assistant to pronounce Englisli words, but you've hit a sag! The resistant is unable to pronounce numbers. When it sees 6243, it just says "six two four three insteud of the proper "six thousand two hundred forty three." Here's where this assignmcut comes in! You'll be writing a set of methods to lielp you truslaterib 's of varying lengths into their English pronunciations Within the 1900 folder on your desktop, create a new folder named Lab6HwLastnameFirstnane. Withiu that folder, create a new class nained Number Pronunciations. Java. All of the metal in hul be written within that class. (3 pts) Problem 1 Let's start with the simplest case: translating a single-digit integer into its English pronunciation. Within NumberPronunciations.java, write a method public static String oneDigitToStr(int n) that returns the pronunciation of n. You may assume that o ns 9. Here are some example arguments for the oneDigitToStr method and their expected rear values: Argument Return Value 0 zero 4 four seven

Answer 1

If you have any problem with the code feel free to comment. The second image is unreadable so I have created the program according to my logic.

Program

import java.util.Scanner;

class NumberToWords {
   private static final String[] digitNames = { "", " thousand", " million", " billion", " trillion", " quadrillion",
           " quintillion" };

   private static final String[] tensNames = { "", " ten", " twenty", " thirty", " forty", " fifty", " sixty",
           " seventy", " eighty", " ninety" };

   private static final String[] oneToNineteenNames = { "", " one", " two", " three", " four", " five", " six",
           " seven", " eight", " nine", " ten", " eleven", " twelve", " thirteen", " fourteen", " fifteen", " sixteen",
           " seventeen", " eighteen", " nineteen" };

   private static String convertLessThanThousand(int number) {
       String word;

       if (number % 100 < 20) {// checking if the number is below 20
           word = oneToNineteenNames[number % 100];
           number /= 100;
       }

       else {// when its not below 20
           word = oneToNineteenNames[number % 10];
           number /= 10;

           word = tensNames[number % 10] + word;
           number /= 10;
       }
      
       if (number == 0)//when number is below hundred
           return word;
      
       return oneToNineteenNames[number] + " hundred" + word;//when number is above hundred
   }

   public static String convert(int number) {

       if (number == 0) {//when number is zero
           return "zero";
       }

       String word = "";
       int place = 0;
      
       //looping through the number and finding its word form
       do {
           int n = number % 1000;
           if (n != 0) {
               String s = convertLessThanThousand(n);
               word = s + digitNames[place] + word;//for thousands to billion
           }
           place++;
           number /= 1000;
       } while (number > 0);

       return word.trim();
   }
}

public class Test {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       int num;
      
       while (true) {
           System.out.print("Enter the integer to pronounce(any negative value to exit): ");
           num = sc.nextInt(); sc.nextLine();
          
           if(num<0) {
               System.out.println("Bye");
               break;
           }
           System.out.println(NumberToWords.convert(num));
           System.out.println();
       }
       sc.close();
   }
}

Output
