How to convert number to words in java

Question

We currently have a crude mechanism to convert numbers to words (e.g. using a few static arrays) and based on the size of the number translating that into an english text. B

Answer 1

I have used 2 dimensional array...

   import java.util.Scanner;


   public class numberEnglish {
   public static void main(String args[])
        {
    String[ ][ ] aryNumbers = new String[9][4];
    aryNumbers[0][0] = "one";
    aryNumbers[0][1] = "ten";
    aryNumbers[0][2] = "one hundred and";
    aryNumbers[0][3] = "one thousand";

    aryNumbers[1][0] = "two";
    aryNumbers[1][1] = "twenty";
    aryNumbers[1][2] = "two hundred and";
    aryNumbers[1][3] = "two thousand";

    aryNumbers[2][0] = "three";
    aryNumbers[2][1] = "thirty";
    aryNumbers[2][2] = "three hundred and";
    aryNumbers[2][3] = "three thousand";

    aryNumbers[3][0] = "four";
    aryNumbers[3][1] = "fourty";
    aryNumbers[3][2] = "four hundred and";
    aryNumbers[3][3] = "four thousand";

    aryNumbers[4][0] = "five";
    aryNumbers[4][1] = "fifty";
    aryNumbers[4][2] = "five hundred and";
    aryNumbers[4][3] = "five thousand";

    aryNumbers[5][0] = "six";
    aryNumbers[5][1] = "sixty";
    aryNumbers[5][2] = "six hundred and";
    aryNumbers[5][3] = "six thousand";

    aryNumbers[6][0] = "seven";
    aryNumbers[6][1] = "seventy";
    aryNumbers[6][2] = "seven hundred and";
    aryNumbers[6][3] = "seven thousand";

    aryNumbers[7][0] = "eight";
    aryNumbers[7][1] = "eighty";
    aryNumbers[7][2] = "eight hundred and";
    aryNumbers[7][3] = "eight thousand";

    aryNumbers[8][0] = "nine";
    aryNumbers[8][1] = "ninty";
    aryNumbers[8][2] = "nine hundred and";
    aryNumbers[8][3] = "nine thousand";


    //System.out.println(aryNumbers[0] + " "+aryNumbers[0] + " ");

    int number=0;
    Scanner sc = new Scanner(System.in);
    System.out.println(" Enter Number 4 digited number:: ");
    number = sc.nextInt();
    int temp = number;
    int count=1;
    String english="";
    String tenglish = "";
    if(number == 0)
    {
        System.out.println("*********");
        System.out.println("Zero");
        System.out.println("*********");
        sc.close();
        return;
    }
    while(temp !=0)
    {

        int r = temp%10;
        if(r==0)
        {
            tenglish = " zero ";
            count++;
        }
        else
        {

            int t1=r-1;
            int t2 = count-1;
            //System.out.println(t1 +" "+t2);
            count++;
            tenglish = aryNumbers[t1][t2];

            //System.out.println(aryNumbers[t1][t2]);
        }
        english = tenglish +" "+ english;
        temp = temp/10;

    }
    //System.out.println(aryNumbers[0][0]);
    english = english.replace("ten  zero", "ten");
    english = english.replace("twenty  zero", "twenty");
    english = english.replace("thirty  zero", "thirty");
    english = english.replace("fourty  zero", "fourty");
    english = english.replace("fifty  zero", "fifty");
    english = english.replace("sixty  zero", "sixty");
    english = english.replace("seventy  zero", "seventy");
    english = english.replace("eighty  zero", "eighty");
    english = english.replace("ninety  zero", "ninety");

    english = english.replace("ten one", "eleven");
    english = english.replace("ten two", "twelve");
    english = english.replace("ten three", "thirteen");
    english = english.replace("ten four", "fourteen");
    english = english.replace("ten five", "fifteen");
    english = english.replace("ten six", "sixteen");
    english = english.replace("ten seven", "seventeen");
    english = english.replace("ten eight", "eighteen");
    english = english.replace("ten nine", "nineteen");
    english = english.replace(" zero ", "");
    int length = english.length();
    String sub = english.substring(length-6,length-3);
    //System.out.println(length);
    //System.out.println(sub);
    if(sub.equals("and"))
    {
        //System.out.println("hello");
        english=english.substring(0,length-6);
    }
    System.out.println("********************************************");
    System.out.println(english);
    System.out.println("********************************************");
    sc.close();
}
