I don't know how to finish this do while loop. Anyone know?

I posted my code based off another discussion post about this question, but the challenge still marked it incorrect.

The question was:

"Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop."
// I have initialized a for you. It is in a variable named console.
String response;

do {

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

String response ="";
           response = console.readLine("Do you understand do while loops?");  // "yes" or "no" is stored in the response variable 
           } while (response.equalsIgnoreCase("no"));

//After the loop exits
console.printf("Because you said %s, you passed the test!",response);

Be aware that code shown in other questions can often have errors (even when posted as an "answer").

But if you use the "preview" button, the output gives you a clue: error: variable response is already defined in method run()
String response = console.readLine("Do you understand while loops? ");
1 error

So your issue here is declaring "response" twice. Only the first line should have the "String" declaration in front.
