I'm stuck here...not the strongest at Java.

having trouble solving task.

Thank you

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?  ");
boolean response;
do {
  response = ();

Try this

String response;

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

If this answers your question, please mark the question as answered

Thanks Mark but unfortunately your recommendation didn't work. ....it tells me in output.html.

JavaTester.java:121: error: variable response is already defined in method run() String response; ^ 1 error

Right

from the error you should deduce that "String response;" has been defined before .

so don't redefine it. Just do

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

and see what happens.

These error messages are great educational tools ... they provides insights into the compiler inner working logic. I learn a lot from them.

Thanks

Great thanks Mark now I know what you mean. These error messages I find tricky at times to deduce what they mean...but live and learn for me lol.

Thanks for your feedback!

Happy coding!
