// I have initialized a java.io.Console for you. It is in a variable named console.
String response = "Yes";
String response;
do {
response = console.readLine("Do you understand do while loops?");
if(response.equalsIgnoreCase("no")){
console.printf("Try again");
}
}while

the do while loop is pretty handy. The statement inside the do-part will be executed at least once. So you can ask the user for input and so on. You should understand that until the consition inside the while parenthesis is true, the do part will be executed.
The loop stops if the condition is false.
So how to write the do-while loop:
do {
//here goes your code that should be executed at least once
} while (condition);
// while the condition is true, repeat the do-part of the loop
// if the condition is false, leave the loop and execute the code below
So the challenge can look like this:
String response;
do {
response = console.readLine("Do you understand do while loops?");
} while (response.equalsIgnoreCase("No"));
// if you say "No", the condition is true and loop goes into do part again
//if you say Yes, the condition is false and the loop is over
console.printf("Because you said %s, you passed the test!", response);
// this line will only be executed if the loop is over - condition of while loop is false
Hope it helps

String response;
do {
response = console.readLine("Do you understand do while loops?");
} while (response.equalsIgnoreCase("no"));

could you mark an answer as best, so other Java-Ninjas could see this.
