title: Making all parameters final with an annotation in Java
body: <p>I've recently been working with Lombok--and I'm wondering it would be possible to provide a class level or method level annotation that adds final to all parameters. For example:</p>
  
  <pre><code>@finalizer
  void foo(Bar bar);
  </code></pre>
  
  <p>Becomes</p>
  
  <pre><code>void foo(final Bar bar);
  </code></pre>
