I don't know how to solve this exercise! Can you please explain me what I did wrong? I dont understand while and do loop

Can someone explain to me how this thing works?

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 asking;
do {
  response = console.readLine("Type yes or no:  ");
  asking = (response.equalsIgnoreCase("no"));
  if (asking) {
    console.printf("Welcome!");
  } while (asking);

Hiya,

For this challenge, you define the String response first, then enter a do while loop.

Inside the loop, you prompt the user with the question provided. At the end of each iteration, you test to see if the answer is "No". If it is, loop again, else don't.

Something like:

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

I hope that makes sense.

Steve.
