console.writeline not working?

Ok, I can't believe I can't figure out something as simple as a console.writeline... but it's not working for me.

// 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?"); } while (response == "No");

console.writeLine ("Because you said " + response + ", you passed the test!");

JavaTester.java:127: error: cannot find symbol console.writeLine ("Because you said " + response + ", you passed the test!"); ^ symbol: method writeLine(String) location: variable console of type MockConsole 1 error

The instructions say, "Finally, using console.printf print out a formatted string...":

  • the challenge is expecting you to use printf and has not defined writeLine
  • it also expects you to use token formatting to build the output string instead of concatenation
