title: Java valuable used as a part of identifier
body: <p>I have a few rows like:</p>
  
  <pre><code>int a1;
  int a2;
  int a3;
  ...
  </code></pre>
  
  <p>And I want a cycle that uses an other integer to identify the specific 'a'.</p>
  
  <p>For example:</p>
  
  <pre><code>int k;
  </code></pre>
  
  <p><code>k</code> gets a random number then I use the <code>a'k'</code> valuable.</p>
