What's the most concise way to get the inverse of a Java boolean value?

Question

If you have a boolean variable:

boolean myBool = true;

I could get the inverse of this with an if/else clause:

if (myBool == true)
 myBool = false;
else
 myBool = true;

Is there a more concise way to do this?

Answer 1

Just assign using the logical NOT ! operator like you do in your condition statements (if, for, while...). You're working with a boolean value already, so it'll change true to false (and vice versa):

myBool = !myBool;

Answer 2

An even cooler way:

myBool ^= true;

And by the way, don't use if (something == true), it's simpler if you just do if (something) (the same with comparing with false, use the negation operator).

Answer 3

myBool = myBool?false:true;
