Ive been stuck for an hour trying to solve the 2nd part of the last challenge of Java Basics - do while loops - (cant imagine the third one)
So far im stuck with this piece of code
Challenge is to continually prompt do while loop with the response as "no". Any help will be greatly appreciated. Thanks.
// 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 badAnswer;
do {
response = console.readLine("Do you understand do while loops? ");
badAnswer = (response.equalsIgnoreCase("no"));
} while (response.equalsIgnoreCase("yes"));

So on the first execution you get input from the user, then over write that by getting input from the user again. The variable does still need to be declared outside the loop. (the boolean variable isn't really needed)
String response;
do {
response = console.readLine("Do you understand do while loops? ");
} while (response.equalsIgnoreCase("no"));

Courses Plus Student 4,511 PointsThank you Allan!
I hate that now that I take a look at your code it seems so easy and logical and when I was trying to solve it by myself, it took me more than an hour and I couldnt even pass it :(
Anyway I will put extra focus and effort on the tips you talked about, specially DRY.
