title: Convert String into List
body: <p>I have List which I use to convert into String:</p>
  
  <pre><code>    private String convertList(List&lt;String&gt; list)
      {
          String listString = "";
  
          for (String s : list)
          {
              listString += s + ",";
          }
          return listString;
      }
  </code></pre>
  
  <p>But I also want to implement the same operation backwards. I want to generate List from String using <code>,</code> as delimiter. How this can be implemented?</p>
