Can someone please help me? I don't know what to do.

I have watched the video twice but I still don't know how to do this task. The question is asking me: "Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop." Could someone please explain me how to do this? -Thank you very much

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  ?")

Ok, so you want to know if user understands while loops, and you will ask him this question util he will say "yes". So first of all you have to declare a string variable named response and initialize it to store "no". Then you have to create a while loop. This is how it looks like : while(condition) {block of code}; Your condition is (response!="yes"); Now inside the loop you have to ask user a question and store his answer in the variable named response. while(response!="yes"){ response = console.readLine("Do you understand while loops?"); } This is what I'm talking about.

I hope now you understand everything.

Have a nice day!

String response ; do{ response = console.readLine("Do you understand do while loops? %n"); } while (response.equalsIgnoreCase("No")); // this can be other option as a Solution, by the way you can use just equals, and not the equalsIgnoreCase, just i did here
