  <p>While reading this from a notepad with the below code i get Array out of bound exception. While debugging i get " ï»¿       #Students" value for strLine.length().
  Can anyone help to solve this? </p>
  
  <pre><code>private static Integer STUDENT_ID_COLUMN = 0;
  private static Integer STUDENT_KEY_COLUMN = 1;
  private static Integer YEAR_LEVEL_COLUMN = 2;
  private static Integer STUDENT_NAME_COLUMN = 3;
  private static Integer TOKEN_COLUMN = 4;
  
  public static void main(String[] args) {
      ArrayList&lt;String&gt; studentTokens = new ArrayList&lt;String&gt;();
  
      try {
          // Open the file that is the first
          // command line parameter
          FileInputStream fstream = new FileInputStream("test.txt");
          BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
          String strLine;
          // Read File Line By Line
          while ((strLine = br.readLine()) != null) {
              strLine = strLine.trim();
  
              if ((strLine.length()!=0) &amp;&amp; (strLine.charAt(0)!='#')) {
                  String[] students = strLine.split("\\s+");
                  studentTokens.add(students[TOKEN_COLUMN]);
              }
  
  
          }
  
          for (String s : studentTokens) {
              System.out.println(s);
          }
  
          // Close the input stream
          in.close();
      } catch (Exception e) {// Catch exception if any
          System.err.println("Error: " + e.getMessage());
      }
  }
