title: Which one to use, int or Integer
body: <p>I need to create a data transfer object, which I will use for storing the records retrieved from database. In this data transfer object, I need to declare a numeric field. For that which one is better - <strong>int</strong> or <strong>Integer</strong></p>
  
  <p>If I am defining the field as Integer, will there be any performance impact because of 'Integer' type if I am going to retrieve more than 2000 records from DB!?</p>
  
  <p>Thanks in advance.</p>
