Need help figuring out whats wrong with this code.

First of all you are missing one bracket at the end of last line - should be ("No")).

Also there is additional } before while which shouldn't be there.

Lastly - adding System.exit(0); will actually kill the loop after first run, regardless what you type.

Side note: don't repeat yourself - initialize the variable outside the loop, then use it. Avoid double declaration.

Code for this challenge should look like this:

// 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.equalsIgnoreCase("no"));
