Java Java Basics Perfecting the Prototype Looping until the value passes

Looping until the value passes

Challenge Task 2 of 3 is giving me nightmares! I can't figure out the syntax. Can someone please walk me through it.

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?");
  isInvalidWord = (response.equalsIgnoreCase("no")

}

Hi Edwin,

Please refer to the following:

//Declare a String variable named response, then initialize it using double quotes
String response ="";


// The do while loop keeps asking the same question until "yes" is entered
//So we want to keep repeating when "no" is typed
// Exit the loop when "yes" is entered

do{
response = console.readLine("Do you understand do while loops?");  // "yes" or "no" is stored in the response variable 
// when someone types "no" the loop repeats
// when someone types "yes" the loop is exited
}while(response.equalsIgnoreCase("no"));

//After the loop exits, the following line prints to the console
console.printf("Because you said %s, you passed the test!",response); //task 3

If you have any other questions feel free to ask!

I kind of get the way you explained it however I entered the syntax but it doesn't work...it says 'compiler error' I believe I entered the code correctly.
