title: Declaring an object of a class as null
body: <p>When we only declare an object of a class without instantiating it like below, does it treats as null or empty or else?</p>
  
  <p>Example1: <code>Directory objDEntry;</code></p>
  
  <p>Example2: <code>Directory objDEntry = null;</code></p>
  
  <p>Is there a difference between Example1 and Example2 or they are same?</p>
