I'm stuck at some question and i don't know how to figure it out. help please

I don't know how to fix this..

Example.java 
// 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?");
String no;
boolean ifItsNo;
do {
     no = console.readLine("Do you understand do while loops?");
     ifItsNo = no.equalsIgnoreCase("No");
     if(ifItsNo)
     {
       console.printf("Do you understand do while loops?");
     }
} while(ifItsNo);

I can see you have kind of the write idea, you're just maybe over complicating it.

You only need to run the loop while response == "No".

The trickiest part about this is that you have to declare the 'response' variable outside of the loop; but you don't have to actually assign it a value you yet. This is due to scoping - you wouldn't be able to evaluate 'response' in the While condition.

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