I am very confused and lost. I am not sure what I am doing wrong.

I am trying to do the loop code and it is not working for me. I tried to go back in the video and check but the code still is not working. Please help!! Thanks!!

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 response;
boolean response; 
do {
  response = console.readLine("No.");

First off String response is already initialized at the top, so creating another variable with the same name will give you an error. Second, for a do while loop it needs to be like so

do {
  //code here will run at least once
} while (boolean condition)

the do loop will always run at least once and will keep running as long as the condition in the while is true.

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

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