title: Which is really a object?
body: <p>So I have a problem trying to figure out if some <code>Object</code> is really created or it's just some kind of pointer.</p>
  
  <p>Can someone help me understand that please?
  I have this kind of example if it helps :)</p>
  
  <pre><code>Bookshelf a = new Bookshelf(2);
  
  Bookshelf b = a;
  
  Bookshelf c = b.clone();
  
  Bookshelf []v ={ a,b,c.clone};
  </code></pre>
