Java8 boolean post unary operator

Does Java 8 have a post unary operator for primitive booleans?

int a = 1;
a++; //look at then increment

boolean bool = true;
???

No, there is no such operator.

Even the ! isn't doing the same as ++ does with numeric types:

  • ++ updates a variable (or array element);
  • ! negates the value of an expression. If applied to a variable, the variable's value is unchanged.

The most similar thing to a "negate operator" would be

(aBoolean ^= true)

but this is "pre-negate", rather than "post-negate".

You can contrive a "post-negate operator" using non-short circuiting operators:

(aBoolean | ((aBoolean ^= true) & false)

But really: don't do this. It's baffling.
