Challenge Task 2 of 3

Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop.

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response
do {
  response = console.readLine("Do you understand do while loops?");
  if (response.equalsInvalidCase("no"))
} while (response.equalsInvalidCase("no"));

Hi Kamil,

delete the if statement inside the while loop. The condition is proofed insede the while statement, you don´t need to set an additional if block. And use the equalsIgnoreCase() method.

And you should be fine.

You don't have to use the equalsIgnoreCase() method. My solution to this challenge was simply:

String response; do { response = console.readLine("Do you understand do while loops?"); } while(response == "No");
