title: Creating an object with a default constructor
body: <p>So say I have this class:</p>
  
  <pre><code>public class PositionList {
      private Position[] data = new Position[0];
      private int size = 0;
  </code></pre>
  
  <p>Now lets say I create a new PositionList object with the default constructor, so no arguments like so:</p>
  
  <pre><code>PositionList list = new PositionList();
  </code></pre>
  
  <p>Does the new list object have any attributes? Does it have a size component or a data component? What are its characteristics?</p>
