Java Java Basics Perfecting the Prototype Looping until the value passes

Variable might not have been initialized Task 2/3

My code looks like it works, but when I click 'preview' it says code might not have been initialized in the boolean, why is this so and how can I fix it?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean isInvalidResponse = (response.equalsIgnoreCase("no") || response.equalsIgnoreCase("no."));
do 
  response = console.readLine("Do you understand do while loops?   \n");
 while (isInvalidResponse = true);

Hi there! On line 2 of your code you declare a String named response. This was not given an initial value. On the line immediately after that you're asking if the response is equal to "no", but response has no value. Response is not given a value until the line after do. Above and beyond that, you will also experience issues after you fix that as your while does not contain a condition, but rather an assignment

:bulb: Hint: Check if the response is equal to "no" on the same line as the while.

Hope this helps! :sparkles:
