Question

Is there a short way to toggle a boolean?

With integers we can do operations like this:

int i = 4;
i *= 4; // equals 16
/* Which is equivalent to */
i = i * 4;

So is there also something for booleans (like the *= operator for ints)?

In C++:

bool booleanWithAVeryLongName = true;
booleanWithAVeryLongName = !booleanWithAVeryLongName;
// Can it shorter?
booleanWithAVeryLongName !=; // Or something?

In Java:

boolean booleanWithAVeryLongName = true;
booleanWithAVeryLongName = !booleanWithAVeryLongName;
// Can it shorter?
booleanWithAVeryLongName !=; // Or something?

Answer 1

There is no such operator, but this is a little bit shorter: booleanWithAVeryLongName ^= true;
