Tokenizer headaches and displaying output - Help!!

Question

Hi all,
I am writing a program that inputs a line of text, converting each word into Pig Latin
(I know it's crazy , but that's what the book wants me to do).... now I am converting
the words ( hello = ellohay, turnip = urniptay, etc etc) just fine... The problem I am experiencing is when I display the whole string of tokens, only the last word is displaying, I am counting the tokens and the count reflects the correct number of words (tokens)... I know it's something stupid ...... I'm sure it's in the "while" logic.....
Thanks in advance
Mike

You for got to put the block that folows the while loop in a block...... change it to like this
while (myTokens.hasMoreTokens() ){
     singleWord = myTokens.nextToken() ;
     StringBuffer modBuffer = new StringBuffer(singleWord) ;
     char charArray[] = new char[modBuffer.length() ] ;
     modBuffer.getChars(     0, 1, charArray, 0 ) ;
     modBuffer.append( charArray[0] ) ;
     modBuffer.append("ay ")     ;
     modBuffer.deleteCharAt(     0 )     ;
     outputArea.append(modBuffer     + "\n")     ;
