Java Java Basics Perfecting the Prototype Censoring Words - Looping Until the Value Passes

Getting an error I can't figure out.

In the following block of code:

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

I am getting the following error:

TreeStory.java:27: error: cannot find symbol
isInvalidWord(noun.equalsIgnoreCase("dork") ||
^
symbol: method isInvalidWord(boolean)
location: class TreeStory
1 error

I'm not sure where it is coming from, and I'm not seeing a difference in my use of the boolean and the one given in the example video. Any help would be appreciated.

Hi William,

You're very close with the answer here. I amended it slightly to:

boolean isInvalidWord;

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

Only 2 things, firstly the variable noun wasn't declared, so I just added String to the front. Secondly, isInvalidWord needed an equals sign after it. In your code, it is being used like a method. It actually needs to be assigned the result from the censored words checks within the brackets.

Hope that helps :)

Thank you! The noun was declared above boolean, I probably should have included that in my code snippet. I don't know how I missed that = sign though. I appreciate the help!
