Can I get a little help my friends?

I followed along with the video, and skipped ahead guessing what I would have to do next. I got a couple of small things wrong, and so I corrected them. When ran the code, it did not work, and I got some errors (2). I thought that they would be easy enough to fix, and so I copied the exact code in the video.

For some reason, it doesn't seem to work for me. I'm pretty sure I've made a silly mistake somewhere, but I can't seem to find it. I'll post my code, and if anyone could point out what is wrong, and how to fix it, I would be most grateful.

            String adjective = console.readLine("Enter an adjective:   ");
            String noun;
            do {
                noun = console.readLine("Enter a noun:  ");
                boolean isInvalidWord = (noun.equalsIgnoreCase("dork") ||
                                                                 noun.equalsIgnoreCase("jerk") ||
                                                                 noun.equalsIgnoreCase("nerd"));
                if  (isInvalidWord) {
                    console.printf("That langauge is not allowed.  Try again. \n\n");
                }
            } while (isInvalidWord);

            String verb = console.readLine("Enter a verb:  ");
            String adverb = console.readLine("Enter an adverb ending in -ing:  ");

Apologies for such a lengthy read! Thanks in advance!

You are running into a scoping error.

do {
                noun = console.readLine("Enter a noun:  ");
                boolean isInvalidWord = (noun.equalsIgnoreCase("dork") ||
                                                                 noun.equalsIgnoreCase("jerk") ||
                                                                 noun.equalsIgnoreCase("nerd"));
                if  (isInvalidWord) {
                    console.printf("That langauge is not allowed.  Try again. \n\n");
                }
            } while (isInvalidWord);

isInvalidWorld is not defined in the scope of the do-while statement. It is only defined within the two curly brackets of the do block. To fix this define the boolean isInvalidWord before the do-while statement:

boolean isInvalidWord;
do {
                noun = console.readLine("Enter a noun:  ");
                isInvalidWord = (noun.equalsIgnoreCase("dork") ||
                                                                 noun.equalsIgnoreCase("jerk") ||
                                                                 noun.equalsIgnoreCase("nerd"));
                if  (isInvalidWord) {
                    console.printf("That langauge is not allowed.  Try again. \n\n");
                }
            } while (isInvalidWord);
