You can't pass variables as arguments to parameters. You pass their values as arguments to parameters.

There is no advantage as much as it's essential. You pass values to methods to make the program work. It's like asking what the advantage of breathing air is.

Please explain. That does not sound correct.

I think BalaMurali might be referring to using the variable itself in another method, much like pass-by-reference in languages such as C.

Yes, it might be possible in pass‑by‑reference.
