Hey Eldin,

A couple of clues:

console.readLine("Do you understand do while loops?");

You are prompting the right question, but are you capturing the response here?

} while(isInvalidWord);

The goal of the task is to prompt the question and store the response. What do you need to test in order for this while loop to end?

Good luck!

You don't need to use a do-while loop.

naming the string:

String response;

prompting the questions:

console.printf("Do you understand do while loops?");

storing the result into the string response:

response = console.readLine();

or you can just combine prompting questions and storing the result:

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