Can anyone help me with this loop

What is wrong with this loop?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response = console.readLine("Do you understand do while loops?  ");
boolean isInvalidWord;
do  {
  isInvalidWord = (response.equalsIgnoreCase("no");
  if (isInvalidWord)  {
    console.printf("Try again.\n\n");
  }
} while(isInvalidWord);

try this:

String response = "no"; while(response.equals("no")) response = console.readLine("Do you understand do while loops? ");

What Nissen may be trying to get at is that you need to get the response from the user inside the do while loop so that the new responses can be tested against "no". Right now, whatever the user first types will be stuck in the response variable and never change.
