Which to use?

If you have a sentence, and you separate it into tokens (which would be the words of the sentence in this case), how would you work with the tokens? Would you work with the original string variable?

Here's what I mean, where this part of code is part of a method. I want to replace every 'a' in the words with an 'e':

    String sentence="insart taxt hara";
    StringTokenizer words = new StringTokenizer (sentence);
    StringBuffer speech = new StringBuffer ();
    String phrase="";
    
    while (words.hasMoreTokens())
    {
      for (int x = 0; x < sentence.length(); x++)
      {
        if (sentence.charAt(x) == 'a')
        {
          sentence = sentence.replace('a', 'e');
        }
      } 
    }
    speech.append(words.nextToken());
    phrase = speech.toString();
    System.out.println(phrase);

while (words.hasMoreTokens())
{
    //...
}
speech.append(words.nextToken());

Doesn't this result in some sort of runtime exception?

It's not really clear what you are trying to do here. If you want to replace all the 'a' characters with 'e' just use replace() once. This has nothing to do with tokenising.

I know that I could do that, but I want to separate the sentence into words and replace the a's separately, word by word.
My compiler's being a pain, I have to check about the error.

My compiler is still having the same problem, it won't run. My cursor just turns into the hourglass.
I would really like to understand this...
