title: check to see if next String tokenizer is empty
body: <p>I'm having a problem, I'm using a text file that has over a million lines of numbers. the data is in the format below, some lines have 3 pieces of data while others have only 2. 
  Each time the file gets to the data with only 2 bits, it seems to throw a null error (I'm using Try/catch to read the input stream)</p>
  
  <p>If I remove the value 3 tokenizer then the program runs to the end. 
  Do I need to put an if statement to check if there is another token after the 2nd line? if so - how??</p>
  
  <pre><code>            while ((getLine = br.readLine()) != null)   {
                StringTokenizer tokenizer = new StringTokenizer(getLine);
                String Value1 = tokenizer.nextToken();
                String Value2 = tokenizer.nextToken();
                String Value3 = tokenizer.nextToken();
              //Does some more things
              }
  </code></pre>
  
  <p>The data</p>
