title: Does it make a difference if I use a default initalisation or no initialisation?
body: <p>Are there any cases that using a default initialization such as:</p>
  
  <pre><code>int myValue;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>MyObject o = null;
  </code></pre>
  
  <p>could change the behaviour of my program compare to cases where I don't initialize the variables at all?</p>
  
  <p>I'm looking for an example.</p>
