Hi there! So for part 1 of the challenge we want to prompt the user with the question of whether they understand do-while loops and store it in the variable "response". This line you have here:

String response= "Do you understand do while loops?";

This is storing the String "Do you understand do while loops?" inside the variable response. Instead we want to store the result of the console.readLine method inside the variable as such:

String response = console.readLine("Do you understand do while loops?");

For part 2 of the challenge we want to continuously prompt the question so long as response is not equal to "No". This would look like the following:

String response; //Declare variable outside of do-while scope 
do {
   //keep asking if they understand do-while loops If answer is "No"
   response = console.readLine("Do you understand do while loops?");
  } while (response=="No"); // If response is NOT equal to "No", stop looping

Hope this helps! take care and happy coding :)
