title: Which one is faster? Integer.valueOf(String string) or Integer.parseInt(String string)?
body: <p>I want to know which method is faster?</p>
  
  <p><code>Integer.valueOf(String string)</code> or <code>Integer.parseInt(String string)</code>?</p>
  
  <p>Is there any Performance or Memory difference between the two approaches?</p>
  
  <p>I have seen <a href="https://stackoverflow.com/questions/508665/difference-between-parseint-and-valueof-in-java">Difference between parseInt and valueOf in java?</a> but this does not explains difference in terms of performance.</p>
