What I am trying to do is set a value in a variable contained within another class.
this is how I am currently trying to achieve it.
BookingUI Class
private void setCarRegNo()
{
aBooking.setCarRegNo();
}
Booking class
public void setCarRegNo(String regNo)
{
carRegNo = regNo;
}
Yet I keep getting an error saying 'setCarRegNo (java.lang.String) in booking cannot be applied to ()
What is it I am doing wrong? Many thanks
You need to pass a String into the setCarRegNo(String ) of Booking class. The method signature declares that it requires a String argument, and your compiler will complain if you dont supply one.
You have to pass a string into the setCarRegNo() function. Like this: setCarRegNo("Some string");
In your Booking Class, setCarRegNo takes a single parameter of type String.
When you call it from BookingUI, you are not passing in any parameters.
You need to change BookingUI to something like:
private void setCarRegNo()
{
aBooking.setCarRegNo("CarRegNo");
}
you need to pass a string to your setter. change
aBooking.setCarRegNo();
to
aBooking.setCarRegNo("the registration number');
as a note, you should fully spell out the words of the variables.
