title: How to resolve `Raw use of parameterized class 'Comparable'` warning?
body: <p>Got to implement the method below for an assignment which it's subject is "WildCards", but don't know where to use wildcards in order to resolve the warning.</p>
  
  <pre><code>static &lt;T extends Comparable&gt; T findMax(T ... items)
  {
      T max = items[0];
      for (T item : items)
          if (item.compareTo(max) &gt; 0)
              max = item;
      return max;
  }
  </code></pre>
  
  <p>Any ideas ?</p>
