Hey Gilbert,

Looking at a past topic: https://teamtreehouse.com/forum/make-sure-you-capture-the-results-from-the-readline-in-the-string-band

String band = console.readLine("Enter input");

Usually whenever I'm asking for input from the user, I leave the parentheses blank.

Example:

ConsoleIO.printLine("Please enter some text.");
String example = ConsoleIO.readLine();

Jacob, yeah, the key issue here is the missing variable type String here; as for the readLine(), it's ok to have something in the parentheses, or just leave an empty string there.
