code wont compile. after 2 hours im beginning to think software is corrupt or this is a joke.

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.

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?");

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

  } while (response == "no");

Hey Chase,

A few things.

First, you'll want to just declare the response variable outside of the loop but not assign it value. Remove the current readLine assignment. The reason being is that we're going to constantly set the value of response within the loop, so that the user is prompted until their response is something other than 'No'.

The last thing to note is that you're going to want to update your while condition. Currently, you're running the loop as long as response is equal to 'no' instead of 'No'. Capitalization matters in this challenge. With that being said, you may be able to take use of equalsIgnoreCase to get around that. Unsure if the challenge's test case will allow that off-hand. 

// I have initialized a java.io.Console for you. It is in a variable named console.
String response;

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

Thanks so much! after all that it was the lowercase "N". its moments like this i wish the syntax error would be more descriptive.
