Java Java Basics Perfecting the Prototype Looping until the value passes

do while loop

It's asking me if I'm looping while the response is No. Can someone tell me what I'm missing?

/ 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 loop: "); boolean isInvalidWord; do { response = console.readLine("Do you understand do while loop: "); isInvalidWord = (response.equalsIgnoreCase("No.")); if (isInvalidWord) { console.printf("Try again. \n\n"); } } while (isInvalidWord);

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 loop:  ");
boolean isInvalidWord;
do {
  response = console.readLine("Do you understand do while loop:  ");
  isInvalidWord = (response.equalsIgnoreCase("No."));
  if (isInvalidWord) {
    console.printf("Try again. \n\n"); 
  }
 } while (isInvalidWord);

While the first

String response = console.readLine("Do you understand do while loop:  ");

is redundant, there is absolutely nothing wrong with your code! Honestly, it is a simple lack of explanation in the challenge. The challenge is looking for the response "No" and you are looking for "No." in your code. All you have to do is remove the period!

I hope this helps! Good luck with the course!
