title: Are Android type parameters also an objects
body: <p>How can it be:</p>
  
  <pre><code>final Button okButton = (Button)findViewById(R.id.okButton);
  </code></pre>
  
  <p>This is very clear that it is a variable declaration + assignment, absolutely not an object !
  If so, how can I do the following, and actually operate a methods on it ?:</p>
  
  <pre><code>okButton.setOnClickListener(this);
  okButton.setOnLongClickListener(this);
  </code></pre>
  
  <p>??</p>
  
  <p>It makes confusion...</p>
  
  <p>Thanks...</p>
