title: Read comma separated text file within Java
body: <p>My text file is like:</p>
  
  <pre><code>1, gold, silver, truck
  2, gold, fire, truck
  3, china, asia, gold, silver, truck, truck
  4, ireland, spain, prague, paris
  </code></pre>
  
  <p>How to jump the first element of the line (1,2,3,4) and read rest of the word one by one?</p>
  
  <p>And how to read only the first element of a row?</p>
  
  <p>Cause I need to store them separatly into two HashMaps.</p>
  
  <p>Thx</p>
