title: Set<Object> vs List<Object>?
body: <p>I have a Object which contains an id and some attributes for that id.</p>
  <pre><code>public class Data {
      private String id;
      private String name;
      private String value;
  }
  </code></pre>
  <p>Currently I have defined it in the Request Object as :</p>
  <pre><code>public class Request {
      private List&lt;Data&gt; dataList;
  }
  </code></pre>
  <p>Is there going to make any difference with List vs Set if I know that I will ll probably never encounter the same id (content) in the request.</p>
  <p>Overall for this usecase, which is better ? List vs Set ?</p>
