Do while loop

Here is my attempt.

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

Hi William. Niced attempt. You have a few syntax errors and missing your while condition.

First Syntax error is you are declaring your string variable response twice. Remove your first line. You will get user input inside the loop.

Second syntax error is you forgot to close your string in the loop. Need a double quote (") after loops? .

Third Syntax error is you forgot to close your do loop with a }

and lastly you need a while condition. without the while a do loop will run forever because it has no way to exit. So what do we want to check for ? We want to "do" our loop "while" response is 'No'. So something like while (response == 'No');

Good luck William and keep at it. Coding is fun but not easy!
