No Preview Error Messages

Hello. I'm being told my code is wrong, but Preview isn't showing any error messages and I don't know where I went wrong. Thanks!

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean doesNotUnderstand;
do{
  response = console.readLine("Do you understand do while loops?  ");
  doesNotUnderstand = (response.equalsIgnoreCase("no"));
  if(doesNotUnderstand){
    console.printf("Try again...");
  }
    } while (doesNotUnderstand);
console.printf("Because you said"  + response + ", you passed the test!");

Hey Riko, try this approach. We can try making the code even more simple than that. 

String response;
do{
response = console.readLine("Do you understand do while loops?");
}
while(response.contains("No"));
console.printf("Because you said %s, you passed the test", response);

Remember using the printf method in our first parameter we can use "%s" to insert our string variable and pass the variable as the second parameter.

Hi, Devin. Thanks for the help. I actually ended up figuring it out moments after I hit send. I was concatenating the String into the code, rather than using %s, as you did in your code. Thanks!
