What is my String.split() not catching here?

Question

Hello,
I am trying to implement the wordcount below. Most of the time it works great, the content matches the wc utility.
Occasionally though it splits in a manner that creates a whitespace word. Any suggestions? Is there a better algorithm to switch to? This had appeared to be a clean approach up until these issues.
public static int wordCounter(File inFile) throws FileNotFoundException, IOException{
          int count = 0;
          BufferedReader inReader = new LineNumberReader(new InputStreamReader(new FileInputStream(inFile)));
          try{               
               String lineString;
               String[] lineWords;     
               //while not the end of the file               
               while( (lineString = inReader.readLine()) != null){
                    lineString.trim();
                    lineWords = lineString.split("\\s+");
                    count += lineWords.length;                    
          } finally{
               //close the BufferedReader
               if(inReader != null){
                    inReader.close();
          //return the count
          return count;
     }

How do I add multiple expressions to my .split()?You don't! You make one expression that does it all.
^[ \t]+|[ \t]+$  <-- remove proceeding and trailing whitespaceNow you just have to figure out how to get your piece in there.
JSGJSG,
I think what the OP meant is s/he wants to know if s/he can use a single regex to split his/her string so that the string
"   a   b   c   "return only three tokens:
["a", "b", "c"]
// or
["   a", "b", "c"]I know of a rather "hackish" way to do it in one split(...) call, but I don't see how your suggestion will make this possible. As far as I can see, you're now just mimicing String's trim() method by using replaceAll(...).
