title: Multiple Map values and I want to return those 3 map values in a single object
body: <pre><code>Map&lt;String, Integer&gt; map1 = new LinkedHashMap&lt;String,
  Map&lt;String, Integer&gt; map2= new LinkedHashMap&lt;String,Integer&gt;();
  Map&lt;String, Integer&gt; map3 = new LinkedHashMap&lt;String,Integer&gt;();
  
  
  
  //dynamic values
  
  map1.put(value1,value2);
  map1.put(value1,value2);
  map1.put(value1,value2);
  
  
  Map.Entry&lt;String,Integer&gt; map1Entry = map1.entrySet().iterator().next();
  Map.Entry&lt;String,Integer&gt; map2Entry = map2.entrySet().iterator().next();
  Map.Entry&lt;String,Integer&gt; map3Entry = map3.entrySet().iterator().next();
  
  
  String keyValue1 = map1Entry.getKey();
  String keyValue2 = map2Entry.getKey();
  String keyValue3 = map3Entry.getKey();
  </code></pre>
  
  <p>I want to return keyValue1, keyValue2, keyValue3. 
  Which is the best way to return in a single object?</p>
