Java Java Basics Perfecting the Prototype Censoring Words - Looping Until the Value Passes

Question about last exercise

I have find the solution for this exercise, but I want to know that why it is not working if I put response = prompt inside the do while loop ? Like This:

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

You should prompt in the loop, otherwise the value never changes.

Let me know if that hint does the trick!

Hi Craig,

I've enjoyed your Java course up until the Extra Credit. After we attempt this section, there's no link to a teacher's solution that one can use to compare with one's solution or if one gets stuck. It would be very helpful if you can provide a link to the teacher's solution for this Extra Credit section so that one can know what one is doing wrong (just like we have in the regular videos) and have the confidence to move forward to the next step.

I believe all treehouse courses with Extra Credit sections should have the teacher's solution links to help those having trouble completing it so that one doesn't have to spend too much time on them instead of moving on to learn the rest of the courses. It just seems like you have to choose between working on the 'Extra Credit' section (which obviously could help you get better) or abandoning it and moving on to learn about the rest of the course so you're not limited to learning a few concepts - which is quite frustrating. You shouldn't have to choose between these two.

Hi Sahil,

I am not sure but I think that String respons must have a variable declaration like this:

String response = " ";

Please correct me if I am wrong


Hi Craig! Thanks for your answer. It works, but I want to know why the code that I have weiten above does not loop? I tought response has the same value as prompt so it should work. I hope you understand what I mean.

It does loop, it just loops indefinitely. Because response is always No, it'll loop until the end of time. response and prompt never change in the looping code, so since it doesn't have a chance to change it just runs that line trillions of times.

Make sense?

Thanks alot I got it.

I think I might have found another reason that it did not work: The console presented the error to me that the code did not work.
