title: RxJava: How to convert List of objects to List of another objects
body: <p>I have the List of SourceObjects and I need to convert it to the List of ResultObjects.</p>
  
  <p>I can fetch one object to another using method of ResultObject:</p>
  
  <pre><code>convertFromSource(srcObj);
  </code></pre>
  
  <p>of course I can do it like this:</p>
  
  <pre><code>public void onNext(List&lt;SourceObject&gt; srcObjects) {
     List&lt;ResultsObject&gt; resObjects = new ArrayList&lt;&gt;();
     for (SourceObject srcObj : srcObjects) {
         resObjects.add(new ResultsObject().convertFromSource(srcObj));
     }
  }
  </code></pre>
  
  <p>but I will be very appreciate to someone who can show how to do the same using <strong>rxJava</strong>.</p>
