*** Ceranith, if you start your array with String[] words = { "Zero", .....[/b] then you don't need to subtract the 1 when you parse the integer, just a suggestion.
You could try it using a hashTable.java.util.Hashtable hashtable = new java.util.Hashtable();
hashtable.put("0", "zero");
hashtable.put("1", "one");
hashtable.put("2", "two");
hashtable.put("3", "three");
hashtable.put("4", "four");
hashtable.put("5", "five");
String str = "1,3,4,4,4";
java.util.StringTokenizer st = new java.util.StringTokenizer(str, ",");
while (st.hasMoreTokens()) {
  String token = st.nextToken();
  String value = (String)hashtable.get(token);
  System.out.println(value);
}or you could go and do it in code, if you don't feel like adding all the numbers from 1 to 1million...
something along the lines of this... not fully working, I couldn't be bothered, sorry ;-)String theNumber = st.nextToken();
String myNumber = "";
if(Integer.parseInt(theNumber) <= 19) { // don't forget your error handling
  myNumber = getNumber(theNumber);
else if( Integer.parseInt(theNumber) <= 99) {
  // loop through the number checking each position in the string
  // This is the difficult part, which I will leave up to you as an
  // exercise (don't you just hate it when people do that ;-)
else if(Integer.parseInt(theNumber) <= 999) {
... etc
public String getNumber(String str) {
  return (String)numbers.get(str);
public String getDecade(String str) {
  return (String)decades.get(str);
private void init() {
numbers.put("0", "zero");
numbers.put("1", "one");
numbers.put("19", "nineteen");
decades.put("2", "twenty");
decades.put("3", "thirty");
decades.put("9", "ninety");
decades.put("10", "one hundred");
private Hashtable numbers = new Hashtable();
private Hashtable decades = new Hashtable();
