Hi Abdellah,

you will need a do-while loop here. The reason is that Inside the do block the user will be asked "Do you understand do while loops?" at least ones. So the user can give the answer.

The while condition proofs the answer and repeats the do block if the answer is no !

Look here:

String response;

do {
response = console.readLine("Do you understand do while loops?");
// thes part will run at least ones
} while (response.equals("No"));
// if the while condition is true 
// repeat the do block

Does it make sense?
