//Here you go, it accepts upper and lower case character of Y theres no need for N because if no Y it's always N 👍 https://code.sololearn.com/c9JUpuU2dlek/?ref=app

What behaviour should your program exhibit if the input is neither Y nor N?

I say take the input as char, then use a simple switch case to return a Boolean

unfortunately I can only use a predefined boolean attribute. Would it still work?

You cant input "Y" and expect the scanner to store true and assign it to as a boolean you need some conditional statements. //I think this will work let me test it my self as I just wrote it... Boolean sc = new Scanner(System.in).nextLine().equals("Y")?true:false;
