title: Connect a string and a double in a ArrayList
body: <p>Is it possible to connect a <code>string</code> and a <code>double</code> in a <code>ArrayList</code> ?<br></p>
  
  <p>It should look this way:<br></p>
  
  <p><code>[itemA 1, itemB 10, itemC 5, ...]</code><br></p>
  
  <p>I tried it with write the <code>double</code> also as <code>String</code> in the <code>ArrayList</code>, but then<br> <code>Collections.sort(list)</code> won't sort the doubles correct.</p>
