Numero

Given any number, convert to plain english:
1 = one
33 = thirty three
635 = six hundred and thirty five
76876586 = seventy six million eight hundred and seventy six thousand five hundred and eighty six

Aims

• Create concise, simple solution
• Test driven development

Approach

• Represent units, teens and tens as an array

• Break integer down into chunks ie. millions, thousands, hundreds etc

• Map blocks onto array ie. 112 = units[1] hunderd and units[(12-10)]

• Worry about the placement of "and's"

• Refactor refactor refactor

  private String [] units = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };
  private String [] teens = { "", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
  private String [] tens = { "", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

To build and run the test suite:
mvn clean install

java -cp target/numero-1.0.jar NumFormatter
