title: List<Object> into CharSequence[]
body: <p>I have a this list:</p>
  
  <pre><code>public List &lt;Book&gt; bookList = new ArrayList &lt;&gt;();
  </code></pre>
  
  <p>You can get Book object's title (which is a CharSequence) using .title on the Book object reference.</p>
  
  <p>And what I want to do is declare a method which would have List of Books as input parameter and return CharSequence[] containing book labels. 
  bookList is sorted albhabeticaly, I would like to keep this if possible.</p>
  
  <p><strong>Edit:</strong> Title is CharSequence too.</p>
