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

If I declare string noun and readline outside do loop and just call it inside do, why does it go into an infinite loop?

String noun = console.readLine("Enter a noun:  ");

      if (noun.equalsIgnoreCase("dork") || noun.equalsIgnoreCase("jerk") || noun.equalsIgnoreCase("stupid"))
        console.printf("That language is not allowed. Try Again\n");
    while (noun.equalsIgnoreCase("dork") || noun.equalsIgnoreCase("jerk") || noun.equalsIgnoreCase("stupid"));

Thank you so much!!!! That question was killing me.

Because the value is never changing, so therefore, the while condition keeps on going. It will go on forever until the condition is true.

That make sense?

Value never changes inside do{} and the inside values cannot access outside values. Yeah!!! Awesome, Thanks!!
