title: Updating CSV rows in Java
body: <p>I have a CSV. Through Java, I am trying to manipulate it. </p>
  
  <p>Let me illustrate through an example - 
   My CSV looks like this :</p>
  
  <pre><code>Deepak, Freddy, 123
  Green, Which, 456
  Reddy, Bluish, 789
  Yellowish, Irish, 987
  Green, Which, 765
  </code></pre>
  
  <p>What I want to do here is - because there are two entries with same value in column one - Green. I want to append the "765" to the second row like "Green, Which, 456, 765" .</p>
  
  <p>I could not find any package in Java, which can update or replace any row of a CSV . Is there any other way of doing this ?
  I am able to do this by creating another CSV and copying the contents of original CSV after manipulating its rows.</p>
  
  <p>Thanks in Advance.</p>
