Do while loops from Java track

Please can someone advise on where I am going wrong with this code? Cant get my head around what errors i am creating!

Example.java
// I have initialized a java.io.Console for you. It is in a variable named console.Strin name=

String response = console.readLine ("Do you understand do while loops?");
int answer = Integer.parseInt (response);
if (answer = no) {
  console.printf("Do you understand do while loops?");
}

String response;
  boolean isInvalidWord;
do {
  response = console.readLine ("Do you understand do while loops?");
isInvalidWord = (response.equalsIgnoreCase ("no"));

if (isInvalidWord) {
  console.printf ("Try again.");

}

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

It may be here:

String response = console.readLine ("Do you understand do while loops?");
int answer = Integer.parseInt (response);
if (answer = no) {
  console.printf("Do you understand do while loops?");
}

because i don't know why you try to parse response to Integer. It is actually possible but not for every string e.g for string "123" It's possible to parse it to 123 Integer, but "no" cannot be parsed like this.

Was it helpful?

The response will be either yes or no.

Do not worry about parsing. Did you get farther through?
