Writing numbers

[Francisco A Guimaraes]

Hi, everybody. I have the following problem: I need to convert a number into text, e.g., if I get '1' I want to convert it to 'One'. Anyone knows if there is a java program that does it? Any help is deeply appreciated.
Thanks,
Francisco

I doubt it...you'll just need a table to pull from to map the numerical numbers with the word versions.
For instance, if the number is between 100 and 1000, you know you'll need to get the first digit (e.g. output "one" for 1, "six" for 6, etc), then "hundred", then do the same with the tens and ones digits.

Here is something that I started for you, if you add to it I would appreciate any additional work. I am sure that there are better ways to do this but this is quick:

  
public static String convert(int intin) {
  int tmp = 0, mtmp = 0, ntmp = 0;
  String digits[] = new String[20];
  String tens[] = new String[10];
  String retrnstr = "";
  digits[0] = "zero";
  digits[1] = "one";
  digits[2] = "two";
  digits[3] = "three";
  digits[4] = "four";
  digits[5] = "five";
  digits[6] = "six";
  digits[7] = "seven";
  digits[8] = "eight";
  digits[9] = "nine";
  digits[10] = "ten";
  digits[11] = "eleven";
  digits[12] = "twelve";
  digits[13] = "thirteen";
  digits[14] = "fourteen";
  digits[15] = "fifteen";
  digits[16] = "sixteen";
  digits[17] = "seventenn";
  digits[18] = "eightteen";
  digits[19] = "nineteen";
  tens[0] = "";
  tens[1] = "ten";
  tens[2] = "twenty";
  tens[3] = "thirty";
  tens[4] = "forty";
  tens[5] = "fifty";
  tens[6] = "sixty";
  tens[7] = "seventy";
  tens[8] = "eighty";
  tens[9] = "ninety";
 
  if (intin < 20)
      retrnstr = digits[intin];
  else if (intin < 100) {
      tmp = intin/10;
      mtmp = intin%10;  
      retrnstr = tens[tmp] + digits[mtmp];
  } 
  else if (intin < 1000) {
      tmp = intin/100;
      mtmp = (intin-100)/10;
      ntmp = (intin-100)%10;
      retrnstr = digits[tmp] + "hundred" + tens[mtmp] + digits[ntmp];
  }
  return retrnstr;  
}

I spent a little more time and did some cleaning and pruning. I have declared the 2 arrays as global and assign the values in the Main. Now I have two simple functions that work up to 99,999:

public static String convert(int intin) {
  String retrnstr = "";
  if (intin < 20)
    retrnstr = digits[intin];
  else if (intin < 100) 
    retrnstr = getTens(intin);
  else if (intin < 1000) 
    retrnstr = digits[intin/100] + "hundred" + 
        getTens(intin-((intin/100) * 100));
  else if (intin < 10000)
    retrnstr = digits[intin/1000] + "thousand" + 
       digits[(intin/100)%10] + "hundred" + 
       getTens(intin-((intin/100) * 100));
  else if (intin < 20000)
    retrnstr = digits[intin/1000] + "thousand" + 
        digits[(intin/100)%10] + "hundred" + 
getTens(intin-((intin/100) * 100));
  else if (intin < 100000)
    retrnstr = tens[intin/10000] + digits[(intin/1000)%10] + 
        "thousand" + digits[(intin/100)%10] + 
"hundred" + getTens(intin-((intin/100) * 100));
  return retrnstr;  
}

public static String getTens(int t) {
  int tmp = 0, mtmp = 0;
  String stmp = "";
  tmp = t/10;
  mtmp = t%10;  
  stmp = tens[tmp] + digits[mtmp];
  return stmp;
}
