title: Select random string from given list
body: <p>I am trying to make Java select 1 random string from a given list.</p>
  
  <p>Example of the list of strings:</p>
  
  <pre><code>1153    3494    9509    2   0   0   0   0
  1153    3487    9509    2   0   0   0   0
  1153    3491    9525    2   0   0   0   0
  1153    3464    9513    2   0   0   0   0
  </code></pre>
  
  <p>Each row is 1 string</p>
  
  <p>The idea is that it selects one, waits a certain period (like 7200 seconds) and replaces the previous string with another random string from the list (could be the same). 
  The loop is sort of infinite.</p>
  
  <p>Does anyone knows how to do this?</p>
  
  <p>Ps.
  I am pretty much noobie with java :S, so i am afraid just saying i should use an arraylist (for example) wont work :P</p>
