title: How to assertThat String is not empty
body: <p>Asserting that a <code>string</code> is not empty in junit can be done in the following ways:</p>
  
  <pre><code> assertTrue(!string.isEmpty());
   assertFalse(string.isEmpty());
   assertThat(string.toCharArray(), is(not(emptyArray())); // (although this didn't compile)
  </code></pre>
  
  <p><strong>My question is</strong>: is there a better way of checking this - something like:</p>
  
  <p><code>assertThat(string, is(not(empty()))</code>?</p>
