There is a method on string called contains. It checks to see if one string is contained within the other. This seems like a good way to build a master list of words that are not allowed. Why don't see if what they typed is in a long string of bad words. After you get that working, attempt to take case into account. If your list of bad words that you maintain is all lower cased, you can check the lower case version of the input in the bad string. How do you make a string lowercase?
boolean isInvalidWord;
String[] badWords = {"dork","jerk"};
do {
noun = console.readLine("Enter a noun: ");
isInvalidWord= false;
for (String ww : badWords) {
if (noun.toLowerCase().contains(ww)) {
console.printf("That language is not allowed. Try again. \n\n");
isInvalidWord = true;
break;
}
}
} while(isInvalidWord);
