I want to change from Syste.out.printf() too println() on main program.

I also want to have not to rely on just five records in afile, have the ooption of having five or a 1000 without having to set the field vaule, is these possible?

So do it. I don't understand the question.

Yes. Have a look at ArrayList.

BTW, please split up that enormous line in your code. It really screws up the windowing software here.

Isn't it funny how there's always time and money enough to do it WRONG?

Why haven’t you got a Student class which encapsulates name and marks? Trying to run two arrays in parallel is error-prone and not good design.
You can have as many lines as you like, but they are a lot easier to add to a List than to an array.
Keep printf(); it is more versatile than println().
