Java Java Basics Perfecting the Prototype Looping until the value passes

I don't know what I am doing wrong. I'm guessing it has something to do with the "if" statement but I don't know.

i

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

  } while (response);

}

Hi Jayden. I think you are working on the second part of the challenge. Good try. In the Do/While you need a condition in the while. If response was a Boolean your loop would work. But response is a string with "Yes" or "No". Since you want the loop running while the user answers "No" you can do something like while (response == "No").

You won't need any of the logic with the if statement if you do it this way. Let me know if you need more help.
