Преобразование числа в слово

Question

Я хотел бы получить помощь по преобразованию целого числа в слово. Я очень новичок в Java, у меня есть представление о том, что я думаю, что я буду делать, но вам нужна помощь.

Код должен печатать слова числа от 0 до 999 и один раз -1, введенный в сканер, программа должна остановиться.

Как это:

Пожалуйста, введите число от 0 до 999: 1

ONE

Пожалуйста, введите число в диапазоне от 0 до 999: 11

одиннадцатая

Введите число от 0 до 999: 122

Сто двадцать два

Пожалуйста, введите число в диапазоне от 0 до 999: 1000

НОМЕРА OUT OF RANGE

Пожалуйста, введите число в диапазоне от 0 до 999: -1

Thank вы для использования нашей программы

я также должны использовать методы, чтобы сделать это «чистый»

Answer 1

Прежде всего взять сотни место цифры разделяющего на 100 и распечатать соответствующий номер с помощью метода numberToWord((number/100), " HUNDRED"); так номер/100 будет находиться в диапазоне от 0 до 9, так что будет печатать цифры в слове каскадного по СТО вызову.

Теперь вы ушли с двухзначным номером, так что вы напрямую звоните numberToWord((number % 100), " ");, так как мы принимаем по модулю 100 номеров, поэтому он будет пропускать только две цифры. if (num > 19) {System.out.print(tens[num/10] + " " + ones[num % 10]);} тогда он займет десятки мест и напечатает десятки слов, объединенных одними. else {System.out.print(ones[num]);} непосредственно печатает слово от 1 до 19 из массива.

import java.util.Scanner; 

public class Test1 { 



     public static void main(String[] args) { 
      int number = 0; 
      Scanner scanner = new Scanner(System.in); 
      System.out.print("Please type a number between 0 and 999 OR type -1 to exit: "); 
      number = scanner.nextInt(); 
      while(number!=-1){ 
       if(number>=0 && number<=999){ 
        if(number==0){ 
         System.out.print("NUMBER AFTER CONVERSION:\tZERO"); 
        } else { 
         System.out.print("NUMBER AFTER CONVERSION:\t"); 
         numberToWord(((number/100) % 10), " HUNDRED"); 
         numberToWord((number % 100), " "); 
        } 

       } else{ 
        System.out.print("NUMBER OUT OF RANGE"); 
       } 
       System.out.print("\nPlease type a number between 0 and 999 OR type -1 to exit: "); 
       number = scanner.nextInt(); 
      } 
     } 

     public static void numberToWord(int num, String val) { 
      String ones[] = {" ", " ONE", " TWO", " THREE", " FOUR", " FIVE", " SIX", " SEVEN", " EIGHT", " NINE", " TEN", " ELEVEN", " TWELVE", " THIRTEEN", " FOURTEEN", " FIFTEEN", " SIXTEEN", " SEVENTEEN", " EIGHTEEN", " NINETEEN" 
      }; 
      String tens[] = {" ", " ", " TWENTY", " THIRTY", " FOURTY", " FIFTY", " SIXTY", " SEVENTY", " EIGHTY", " NINETY"}; 
      if (num > 19) { 
       System.out.print(tens[num/10] + " " + ones[num % 10]); 
      } else { 
       System.out.print(ones[num]); 
      } 
      if (num > 0) { 
       System.out.print(val); 
      } 
     } 
    } 

Пример вывода:

Please type a number between 0 and 999 OR type -1 to exit: 563 
NUMBER AFTER CONVERSION:  FIVE HUNDRED SIXTY THREE 
Please type a number between 0 and 999 OR type -1 to exit: 45 
NUMBER AFTER CONVERSION:  FOURTY FIVE 
Please type a number between 0 and 999 OR type -1 to exit: 6 
NUMBER AFTER CONVERSION:  SIX 
Please type a number between 0 and 999 OR type -1 to exit: 0 
NUMBER AFTER CONVERSION: ZERO 
Please type a number between 0 and 999 OR type -1 to exit: -1 
exit 

Answer 2

Это рекурсивное решение номер в программе Word,

string unitsMap[] = { "zero", "one", "two", "three", "four", "five","six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; 
string tensMap[] = { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" }; 

string NumberToWords(int number) 
{ 
if (number == 0) 
    return "zero"; 

if (number < 0) 
    return "minus " + NumberToWords(abs(number)); 

string words = ""; 

if ((number/1000000000) > 0) 
{ 
    words += NumberToWords(number/1000000000) + " billion "; 
    number %= 1000000000; 
} 

if ((number/1000000) > 0) 
{ 
    words += NumberToWords(number/1000000) + " million "; 
    number %= 1000000; 
} 

if ((number/1000) > 0) 
{ 
    words += NumberToWords(number/1000) + " thousand "; 
    number %= 1000; 
} 

if ((number/100) > 0) 
{ 
    words += NumberToWords(number/100) + " hundred "; 
    number %= 100; 
} 

if (number > 0) 
{ 
    if (number < 20) 
     words += unitsMap[number]; 
    else 
    { 
     words += tensMap[number/10]; 
     if ((number % 10) > 0) 
      words += "-" + unitsMap[number % 10]; 
    } 
} 

return words; 
} 

Answer 3

Вот как вы это делаете. Я сделал это от 1 до 10, но вы можете расширить его с 1 до 999.

//  values entered  |  result 
    //  2      |  You have entered:Two 
    //  10     |  You have entered: Ten 
    //  23     |  You have entered: 23 which is not in range. 

int i = Integer.parseInt(txtInput.getText()); 
    String[] namesOfNums = {"One", "Two", "Three","Four", "Five", "Six", "Seven","Eight", "Nine","Ten" }; 
    String output = ""; 
    if (i > 0 && i <=10) 
    { 

     output = namesOfNums[i - 1]; 
     lblDisplay.setText("You have entered: "+ output); 

    } 
    else 
    { 
     lblDisplay.setText("You have entered: "+ i +" which is not range."); 
    }

попробовать это для одной цифры:

public class WordToNumber {

static String st1[] = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"}; 
static int st2[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}; 

public static int mac(String n) { 
    int digit = 0; 
    try { 
     if(Arrays.asList(st1).contains(n.toLowerCase())){ 
      int a = Arrays.asList(st1).indexOf(n.toLowerCase()); 
      digit = st2[a]; 
     } 
     else{ 
      return -1; 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
     return -1; 
    } 
    return digit; 
} 

}
