Java Java Basics Perfecting the Prototype Looping until the value passes

Am I on the right track with the first question?

Having a hard time understanding the whole do while loop thing. I'm not really understanding the question being asked either. please help and explain, Thanks!

Question: Prompt the user with the question "Do you understand do while loops?" Store the result in a new String variable named response.

Example.java
// I have initialized a java.io.Console for you. It is in a variable named console.
String response 
do {  
  console.printf("Do you understand do while loops?");

Hey Treshawn,

In the first challenge, you simply need to declare a String variable called response and assign it the value returned from the readLine method.

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

Next, as we set-up our do-while loop, we'll want to move the initialization of response to the inside of our loop. The reason being that each time through the loop, response will be updated with a new value.

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

Now, we'll want to run this loop while the value of response is equal to "No".

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