title: get JSONArray value from key in Multimap
body: <p>I have a multimap.</p>
  
  <pre><code>Multimap&lt;String,JSONArray&gt; map = ArrayListMultimap.create();
  </code></pre>
  
  <p>I am trying to get all values based from key. But when I am trying, I am getting the following error:</p>
  
  <pre><code> Exception details:  java.lang.ClassCastException: 
   com.google.common.collect.AbstractMultimap$RandomAccessWrappedList cannot be 
   cast to org.json.JSONArray
   java.lang.ClassCastException: 
   com.google.common.collect.AbstractMultimap$RandomAccessWrappedList cannot be 
   cast to org.json.JSONArray
  </code></pre>
  
  <p>I am trying to do :</p>
  
  <pre><code>for (final String str : map.keySet()) {
              final JSONArray jsonArr = (JSONArray) map.get(str);
             //do something
  }
  </code></pre>
  
  <p>Can anyone suggest how to get the jsonArray for each keyset?</p>
