OFFTOPIC: Scriptlet para numeros en literal en jasperreports

Queria compartir este scriptlet, una clase java para crear funciones especificas en jasper reports, que estaba usando para un reporte en para mostrar los numeros en literal, muy utilizados en facturas.

Bueno no es un post directamente relaciondo a WaveMaker pero quize compartir para que puedan incluirlo en sus aplicaciones.

Aqui la clase en java.

import java.text.DecimalFormat;

public class EnglishNumberToWords extends JRDefaultScriptlet{

  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", " ");
  }

 }




y desde el ireport podemos usar este scriptlet.

Espero que les sirva.
