371 Pointscode is correct
I'm getting an error with the below code, but I think it's correct:
String response;
boolean isInvalidResponse; do { response = console.readLine("Do you understand do while loops?"); isInvalidResponse = (response.equalsIgnoreCase("No")); } while(isInvalidResponse);
console.printf("Because you said " + response + ", you passed the test!");
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean isInvalidResponse;
do { response = console.readLine("Do you understand do while loops?");
isInvalidResponse = (response.equalsIgnoreCase("No"));
} while(isInvalidResponse);
console.printf("Because you said " + response + ", you passed the test!");

console.printf("Because you said %s, you passed the test!",response);

console.printf("Because you said %s, you passed the test!", response);

371 Pointsindeed that's exactly what I was trying it to do.

371 Pointsthis was in response to challenge 3 of 3 of Java basics "Finally, using console.printf print out a formatted string that says "Because you said <response>, you passed the test!""
- just needed to add a console.printf with the variable in the middle of the text, which I think I did correctly, do you think this is a bug with the editor or did I do something wrong with my code?

Treehouse Moderator 11,075 PointsNo his printf was wrong, the way he performed equalsIgnoreCase was also correct, the code was just expecting proper usage of printf.

371 Pointsbrilliant thanks! (it worked) but I thought I could add variables in between printf output text with a + is this not correct?
