Inverting value of boolean variable?

[redZERO]

Hi guys,

I am using boolean variables as flags in a program and i want to be able to invert the value.

for example if the current value is true, then it must be changed to false; doesn't matter if i don't know what the current value is.

Use the ! operator.

boolean a = true;
        System.out.println (Boolean.toString(a)); // true
        a = !a;
        System.out.println (Boolean.toString(a)); // false

Excellent, thank you very much!
