there is probably a lotmore wrong here but it says it cant find symbol on the while loop line

Cant find how to get a response

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

You need to declare your "response" string with empty quotes then go into the loop prompt the user for response then go down to your while condition and put while(response.equalsIgnoreCase("No"));

Then jump down and put a printf that says console.printf("Because you said %s, you passed the test!", response);

That's all there is to it.

You don't need the Boolean in there.
