Counting Lines/Char/Words in a txt file

Question

I created this method that counts the mount of lines/words/ and char in a file. But for somereason, its not working correctly. Its giving me numbers that are a little off.
     // Method countLineWordChar counts the number of lines, words, and chars, in
     // a file given as a parameter. This method returns an array of intergers. In
     // the array, the first position is the amount of lines, the second posistion
     // is the amount of words, and the third is the amount of chars.
     public static int[] countLineWordChar(File f)
          int[] countInfo = new int[3];
          int lineCount = 0;
          int wordCount = 0;
          int charCount = 0;
          try
               FileReader fr = new FileReader(f);
               StreamTokenizer st = new StreamTokenizer(fr);
               st.eolIsSignificant(true);
               while(st.nextToken() != StreamTokenizer.TT_EOF)
                    switch(st.ttype)
                         case StreamTokenizer.TT_WORD:
                         wordCount++;
                         String wordRead = st.sval;
                         charCount += wordRead.length();
                         break;
                         case StreamTokenizer.TT_EOL:
                         lineCount++;
                         break;
                         default:
                         break;
          catch (FileNotFoundException fnfe)
               UserInterface.showFileNotFoundError();
          catch (IOException ioe)
               JOptionPane.showMessageDialog(null, ioe.toString(), "Error",
               JOptionPane.ERROR_MESSAGE);
          countInfo[0] = lineCount;
          countInfo[1] = wordCount;
          countInfo[2] = charCount;
          return countInfo;
     // Based on the countLineWordChar method, returns the amount of lines.
     public static int getLineCount(int[] countInfo)
          return countInfo[0];
     // Based on the countLineWordChar method, returns the amount of words.
     public static int getWordCount(int[] countInfo)
          return countInfo[1];
     // Based on the countLineWordChar method, returns the amount of chars.
     public static int getCharCount(int[] countInfo)
          return countInfo[2];
     }

Well, for one thing, you're adding the number of characters in words, not the number of characters overall. Are you sure it's not supposed to be the latter?
Otherwise, how is it off?
Basically the way you fix this kind of thing is to add debugging code, then give it a small data sample and watch the debugging messages.
By the way, returning an array of different kinds of values like that isn't ideal. In this case it's not so bad, because the kinds of values are actually really similar -- they could be viewed as a tuple. But don't make a habit of it. An example of a bad application of this would be if you were returning an array that counted, say, the weight of a ship, the length of its hull, and the distance it travelled in the last year. The alternative is to create a class that encapsulates the data being returned, or to move functionality around so the data isn't being returned at all.
