title: Is there an increment operator ++ for Java enum?
body: <p>Is it possible to implement the <code>++</code> operator for an enum?</p>
  
  <p>I handle the current state of a <a href="https://en.m.wikipedia.org/wiki/Finite-state_machine" rel="noreferrer">state machine</a> with an enum and it would be nice to be able to use the <code>++</code> operator.</p>
