title: Sort Map<String, List<Object[]>>
body: <p>Is there an efficient way of sorting a Java Map that has List as value?
  I have string as a key, and I'm trying to sort values that I have in my Object List.</p>
  
  <pre><code>Map&lt;String, List&lt;Object[]&gt;&gt; liste = new TreeMap&lt;String, List&lt;Object[]&gt;&gt;();
  </code></pre>
