Tokenizer not retaining its value

Question

Again another issue I do not understand! Would anybody understand this?
The Tokenizer does not retain its value!? Why it does not?
15,XCV, Some Other String, 10',389.5,4194.0
while ((rec = aPrintData[rIndex].toString()) != null){
     Iterator tokZ = new myNewGetToken(rec, patS, retD);
         for(; tokZ.hasNext();){               // here I got the value 15
              tokZorRetD = (String)tokZ.next();     // here I got "NULL"???
              if (tokZorRetD == null) {
                   patScount--;
                   mCount--;
              }else{
                   switch(patScount){
public class myNewGetToken implements Iterator{
//          class RETokenizer implements Iterator{
          private CharSequence in;
          private Matcher mt;
          boolean retD;
          private String delim;
          private String match;
          private int lastEnd = 0;
          public myNewGetToken(CharSequence in, String patS, boolean retD){
              this.in = in;
              this.retD = retD;
              Pattern pattern = Pattern.compile(patS);
              mt = pattern.matcher(in);
          public boolean hasNext(){
               if(mt == null){
                    return false;
               if(delim != null || match != null){
                    return true;
               if(mt.find()){
                    if(retD){
                         delim = in.subSequence(lastEnd, mt.start()).toString();
                    match = mt.group();
                    lastEnd = mt.end();
               }else if(retD && lastEnd < in.length()){
                    delim = in.subSequence(lastEnd, in.length()).toString();
                    lastEnd = in.length();
                    mt = null;
               return delim != null || mt != null;
          public Object next(){    // the value is not there anymore
               String result = null;
               if(delim != null){
                    result = delim;
                    delim = null;
               }else if(match != null){
                    result = match;
                    match = null;
               return result;
          public boolean isNextToken(){
               return delim == null && match != null;
          public void remove(){
               throw new UnsupportedOperationException();
     }I renamed it because I might need to modify or find out why it does not keeps the value!

dubwai, I am sure you doubt the programming solutions
that I come up with BUT while I run into many problems
to get the results right it seems like that has to be
done what the man has to do!I don't doubt it. I'm 100% absolutely sure that your 'fix' doesn't change anything.
Let me explain line by line:
tempToken = tokZ.next();   //  do Not convert do Not cast, keep it as ObjectThe Object is what it is. Casting the Object doesn't change it. All it does at runtime is check to see
that the given Object is String or what ever you cast it to: Try the following:
Object o = "test";
String s = (String) o;
System.out.println("o and s are the same Object? " + o == s);
tokZorRetD = (String)tempToken.toString();  // Now, convert and cast
// would that have to do anything with StrongTyping?Given that your previous code was not throwing a ClassCastException, the Iterator is already
a String. Calling toString on a String just returns this:
String s = "test"
System.out.println("s.toString returns s? " + s == s.toString());Also, toString returns a String. There's no need to cast a String to String.
And if s is null (which it appears to sometimes be) calling toString() will throw a NullPointerException.
In short, if your code has been fixed, it was something else.
