title: Any way to force classes to have public static final field in Java?
body: <p>Is there a way to force classes in Java to have public static final field (through interface or abstract class)? Or at least just a public field?</p>
  
  <p>I need to make sure somehow that a group of classes have </p>
  
  <p><code>public static final String TYPE = "...";</code> </p>
  
  <p>in them.</p>
