    thanks!

    class Bool
    {

    Default Re: simple change to a boolean value in a method call help...

    Hello rptech. Welcome to the Java Programming Forums

    You are getting this error because you are setting the variable 'result' twice.

    You only have to make a very small change:

    class Bool {
     
        public static void main(String[] args) {
     
            boolean result = false;
            System.out.println("The boolean is before call " + result);
     
            ChangeBool(result);
            System.out.println("The boolean returned after call to method "
                    + result);
        }
     
        public static boolean ChangeBool(boolean result) {
     
            [B]result = true;[/B]
            System.out.println("Change boolean value, result is " + result + " in method");
            return result;
        }
    }
