Issue w Java

I have a 'do while' loop and for the loop to end the 'isInvalidWord' has to equal false.

I am checking if a curse word is in a string, and I was wondering how to also use 'equalsIgnoreCase' while checking if the string has an invalid word.

I have no idea how to put 'isInvalidWord = string.contains(curseWord));' and 'isInvalidWord = string.equalsIgnoreCase(curseWord));' in the same variable.. I have tried '&&', but I am not very good with all this stuff.

Sorry for the confusion.

Hi Zach,

posting your code would be helpful in gerneral. I think you could convert your string to lowercase (.toLowerCase() )and then do string.contains(curseWord).

do
        {
            //Getting insult
            System.out.println("Throw your best insult at me, bet you can't insult me.\n");
            String insult = s.nextLine();

            //Checking if insult has a curse word
            isInvalidWord = (insult.contains(curseWord));


            //Filtering Words
            if (isInvalidWord)
            {
                System.out.println("Try that insult again, just without cursing.\n");
            }

            //Looping if insult does have a curse word(s)
        }while (isInvalidWord);
        //Output once conditions are met
        System.out.println("Oucchh! That was a good one.\n");

I think you can try it this way?

with method chaining, you can bring user reply to a lowercase and make sure curseWord is lowercase. 

// original code
isInvalidWord = (insult.contains(curseWord));

// bring insult to lowercase not having to deal with case sensative anymore
isInvalidWord = (insult.toLowerCase().contains(curseWord)); 

// or this if you haven't put curseWord all to lowercase. 
isInvalidWord = (insult.toLowerCase().contains(curseWord.toLowerCase()));
