title: Wrapper Classes, Difference in functionality when creating object via a String parameter in Constructor?
body: <p>In terms of instances of wrapper classes, does the instance behave differently when the instance is created via a <code>String</code> arg in the constructor in comparison to an <code>int</code>, <code>double</code> etc. </p>
  
  <p>E.g is there a difference in:</p>
  
  <pre><code>Integer wrapperInt= new Integer(33);
  
  Integer wrapperInt2= new Integer("33");
  </code></pre>
