Hey Sha Sud, next time please give more info, like which step of the task you are on. You get initialization error because you declare String response, but you do not initialize it - do not give it a meaning. In a while statement you are checking if your String response is equal to "no", but you never gave it a meaning. You should put an answer from readLine to the String response. Tell me how it goes.

The code you posted has issues as below:

  1. The first pair of curly braces are redundant.
  2. After reading the user input, it is not being assigned to "response" String.

Here is a solution:

String response;

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

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