Getting file character count

[Dillinger4]

Im trying to get the character count of a file which contains only my name "Brandon". The problem is that i am getting two different results for the character count. The first System.out.println() returns the correct count and the second a result of 11 characters. This makes no sense to me. Any help would be appreciated. Thanks.

 public int getFileCharCount(String file) {

    String lineOnebyOne = null;
    String finalText = null;
    int numberOfChar = 0;
  try{
    BufferedReader br = new BufferedReader(new FileReader(file));
    while((lineOnebyOne = br.readLine()) != null){
     
      finalText += lineOnebyOne;
        System.out.println(lineOnebyOne.length());
         System.out.println(finalText.length());
    }
     
      numberOfChar = finalText.length();
     br.close();
     }catch(IOException e){System.err.println(e + "getFileCharCount");}
      
       return numberOfChar;
   }
