it says that prepareAttempt in Home.java cannot be applied to (boolean).

Guys:

This line is not working mTimeLine.setOnFinished(e -> { prepareAttempt(mCurrentAttempt.getKind() == AttemptKind.FOCUS) ? AttemptKind.BREAK : AttemptKind.FOCUS; }); } It says that prepareAttempt cannot be applied to boolean. Where did boolean come from?

I believe this has to do with how your parentheses are lined up.

mTimeLine.setOnFinished(e -> { prepareAttempt ( mCurrentAttempt.getKind () == AttemptKind.FOCUS ) ? AttemptKind.BREAK : AttemptKind.FOCUS; });

The way these two (bolded above) are set up mean you are calling prepareAttempt on "mCurrentAttempt.getKind () == AttemptKind.FOCUS" which in itself returns a boolean value. You should reorder you parentheses to

mTimeLine.setOnFinished(e -> { prepareAttempt(mCurrentAttempt.getKind () == AttemptKind.FOCUS ? AttemptKind.BREAK : AttemptKind.FOCUS)});

so that AttemptKind.FOCUS ? AttemptKind.BREAK : AttemptKind.FOCUS can actually decipher which mode you are in

Hi Matthew,

Thank you for your help. Yes, it was in parentheses. It's all fixed now.

Have a great day and thanks again

Kind regards Mojo
