title: Declaration of wrapper classes
body: <p>This question is in continuation to a question <a href="https://stackoverflow.com/questions/17489250/how-can-a-string-be-initialized-using/17489410">How can a string be initialized using &quot; &quot;?</a></p>
  
  <p>I would like to raise your attentation that even <code>Integer</code>, <code>Double</code>, <code>Character</code>, <code>Float</code>, <code>Boolean</code> wrapper class can also be declared in the same way <code>String</code> is declared like:</p>
  
  <pre><code>String s = "Test string"
  
  Integer i = 10; //valid
  Double d = 10.00; //valid
  Boolean b = true; //valid
  </code></pre>
  
  <p>Does these class are also given special treatment like the <code>String</code> class.</p>
