java - Int から Java の英単語へ

Question

ここで私は奇妙なことを尋ねます。

整数値を、その数値を表す英語の単語を含む文字列値に変換できる方法/ロジックはありますか?

たとえば、ユーザーは 22 を入力し、出力 22 または 2 を取得します。

ありがとう

Answer 1

このコードをチェックしてください。探しているものかもしれません。たとえば、main メソッド内に次のようなものがあるとします。

System.out.println(convert(22));

出力：

twenty two

編集私は以下のコードを再現し、フォーマットを少し整理しました（メインメソッドは一番下にあります）：

import java.text.DecimalFormat;

public class EnglishNumberToWords {

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

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

    private static String convertLessThanOneThousand(int number) {
        String soFar;

        if (number % 100 < 20) {
            soFar = numNames[number % 100];
            number /= 100;
        } else {
            soFar = numNames[number % 10];
            number /= 10;

            soFar = tensNames[number % 10] + soFar;
            number /= 10;
        }
        if (number == 0)
            return soFar;
        return numNames[number] + " hundred" + soFar;
    }

    public static String convert(long number) {
        // 0 to 999 999 999 999
        if (number == 0) {
            return "zero";
        }

        String snumber = Long.toString(number);

        // pad with "0"
        String mask = "000000000000";
        DecimalFormat df = new DecimalFormat(mask);
        snumber = df.format(number);

        // XXXnnnnnnnnn
        int billions = Integer.parseInt(snumber.substring(0, 3));
        // nnnXXXnnnnnn
        int millions = Integer.parseInt(snumber.substring(3, 6));
        // nnnnnnXXXnnn
        int hundredThousands = Integer.parseInt(snumber.substring(6, 9));
        // nnnnnnnnnXXX
        int thousands = Integer.parseInt(snumber.substring(9, 12));

        String tradBillions;
        switch (billions) {
        case 0:
            tradBillions = "";
            break;
        case 1:
            tradBillions = convertLessThanOneThousand(billions) + " billion ";
            break;
        default:
            tradBillions = convertLessThanOneThousand(billions) + " billion ";
        }
        String result = tradBillions;

        String tradMillions;
        switch (millions) {
        case 0:
            tradMillions = "";
            break;
        case 1:
            tradMillions = convertLessThanOneThousand(millions) + " million ";
            break;
        default:
            tradMillions = convertLessThanOneThousand(millions) + " million ";
        }
        result = result + tradMillions;

        String tradHundredThousands;
        switch (hundredThousands) {
        case 0:
            tradHundredThousands = "";
            break;
        case 1:
            tradHundredThousands = "one thousand ";
            break;
        default:
            tradHundredThousands = convertLessThanOneThousand(hundredThousands)
                    + " thousand ";
        }
        result = result + tradHundredThousands;

        String tradThousand;
        tradThousand = convertLessThanOneThousand(thousands);
        result = result + tradThousand;

        // remove extra spaces!
        return result.replaceAll("^\\s+", "").replaceAll("\\b\\s{2,}\\b", " ");
    }

    public static void main(String[] args) {
        System.out.println(convert(22));  // "twenty two"
    }
}

Javaの整数範囲全体をヒングリッシュ表記に変換できる非常に単純なソリューションがあります

    String h1[] = { "Zero", "One", "Two", "Three", "Four", "Five", "Six",
                "Seven", "Eight", "Nine", "Ten", "Eleven", "Tweleve", "Thirteen",
                "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen",
                "Nineteen" };
        String h2[] = { "Twenty", "Thirty", "Fourty", "Fifty", "Sixty", "Seventy",
                "Eighty", "Ninety" };
        String h3[] = { "Hundred", "Thousand", "Lakh", "Crore", "Arab" };

public String parseToHinglishNotation(int num) {
        String word = "";

        if (num < 0) {
            word += "Minus ";
            num = -num;
        }

        if (num < 20) {
            word += h1[num];
        } else if (num < 100) {
            int temp = num / 10 - 2;
            word += h2[temp];

            temp = num % 10;
            if (temp > 0) {

            }
        } else if (num < 10000000) {
            int temp = num / 100000;
            word += parseToHinglishNotation(temp) + " " + h3[2];

            temp = num % 100000;
            if (temp > 0) {
