where instance variables get initialized
<pre><code>public class Ex
{
  int a;
  public Ex()
  {
      System.out.println("a is "+a);
   }
}
</code></pre>

<p>output is:a is 0</p>

<p>where a gets initialized...</p>

<p>i know that default values for int is zero..my question is that where it gets initialied ..through default constructor ?(i heard that default constructor is created when we don't mention any constructor in the class) </p>
