Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don'

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

do { response= console.readLine("enter a response"); badWord=(response.equalsIgnoreCase("no")); if (badWord) { console.printf("try again /n"); } }while (badWord);

}

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?");
String response;
boolean badWord;

do { 
  response= console.readLine("enter a response");
  badWord=(response.equalsIgnoreCase("no"));
        if (badWord) {
        console.printf("try again /n");
        }
}while (badWord);

You don't need the first line of code anymore String response = console.readLine("Do you understand do while loops?");

it is already in your do while loop

hope that helps

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.
