Can you please let me know where I went wrong?

I am getting error msg for this code. Can anyone please let me know where I went wrong?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

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

  if(response.equalsIgnoreCase("No"))
  {
       console.printf("Going back to the loop");}
}

Hi there,

You are creating a do/while loop. This will loop while a condition remains true. In this case, it loops while the answer remains as "No".

The structure of a loop is like this:

do {
  // keep doing this
} while (condition == true);

So, bin your if statement and move the condition, response.equals("No") inside the while brackets.

You end up with something like:

String response;
do {
  response = console.readLine("Do you understand while loops?: ");
}while(response.equals("No"));

Let me know how you get on.

Steve.
