title: parse a specific column by its header in Java
body: <p>This is what my CSV file looks like :</p>
  
  <pre><code> X, X2, Symbol, Date, Open, High, Low, Close, Volume
  
   5, 9, AAPL, 01-Jan-2015, 110.38, 110.38, 110.38, 110.38, 0
   2710, 289,  AAPL, 01-Jan-2015, 110.38, 110.38, 110.38, 110.38, 0
   5415, 6500, AAPL, 02-Jan-2015, 111.39, 111.44, 107.35, 109.33, 53204600
  </code></pre>
  
  <p>How can I select values only from X and X2 columns? I've been trying with openCSV library but got nothing good.</p>
  
  <p>Thanks</p>
