Basic variable issue

Posted: Apr 6, 2010 12:20 AM

I have a very basic issue- I have a method as follows:

 public void makeBooking(String name, int time)
    {
        bookings[time] = name;
    }

and when I call that method, giving it input of say fred and 2, it says "Error: cannot find symbol - variable fred". For some reason, I can't pass a String argument in- any other argument type seems to work fine however?

Is the String that you're passing in, in quotes? i.e.

    makeBooking("fred", 2);

I'm guessing that you've actually written...

    makeBooking(fred, 2);

In the latter case, the compiler thinks that fred is a variable that holds the actual name that you want to pass in. Other arguments (i.e. numbers) don't require quotes because - for them - it's obvious when you're talking about a value and when you're talking about a varible holding a value.

Alternatively, you could write:

    String fred = "Joe";
    makeBooking(fred, 2);

But that's probably just going to confuse things.
