Java Basics Do While error

Hello there ;)

I'm also a novice, so feel free to correct me, if I'm wrong.

You don't have to ask for the input twice - you did it once outside the loop, and second time inside it. Erase the 'answer' string, and leave the 'response' declared, but initialize it first inside the do while loop. It may solve your problem, and keep your code a little cleaner. I have also used the .equalsIgnoreCase(), to compare it to the response string inside mine while parenthesis. You might want to try it out too, but I don't think there should be a problem with your way.

I hope I was able to help. :) Best regards, Marek

Your loop seems like it should be working alright, though there is one error with your last printf; you forgot to add the parameters for the %s.

console.printf("%s, good answer, It's good to understand do while loops!", answer);

The code-challange says there is an error with your loop though, so perhaps this won't fix your issue. Try it, and let me know!

EDIT:

Alright, I tried the code-challange my self and here is what I did:

// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
do {
  response = console.readLine("Do you understand do while loops?");
} while (response == "No");
console.printf("Because you said %s, you passed the test!", response);

Still not sure what's wrong with your code, because the loop really should work the way you've written it. But perhaps the code-challange doesn't like something else in your code and gives you that message even though the loop it self is correct. Though you have some prints and other stuff that seems improvised. The code-challange system is usually picky on improvised code, even if it's not "wrong" -- try and follow the instructions exactly as they are presented.
