Thread: File IO

File IO is a large subject, and what I really find confusing about
it is that nearly anywhere you look for information on it, you find
a morass of different methods listed on how to read or write to
files, but nothing that really sorts them out from each other, as
to why you would use one method over another.

Does anyone know of a good tutorial site the makes this all clear?

Oracle's site has one that goes over the methods, but nothing
explaining why you would use one method over the other in a clear
manner, and the whole Java API is not much help in that regard
either, although I can say that it beats the hell out of Microsoft's
Visual Basic API!

I think you are looking for tutorial on nio (new IO) released by Oracle since JDK 5.

Well, I am really looking for something that expands on this:
Reading, Writing, and Creating Files (The Java™ Tutorials > Essential Classes > Basic I/O)

AND any other forms, including nio. Reason is, I want to know File IO well, as
I expect that I will be taking the Java certification exam that includes that in the
future. I suppose the best way to word the question is, is there an
all-encompassing tutorial (or book) out there that explains why you would use
one method over the other, that is all-inclusive of the different methods that
can be used!

I doubt if you could get all in one kind of tutorial but you can surely get tutorial of operations like reading, writing file etc.

Find a book with a thorough chapter on File IO, the Deitel books are the most thorough I've seen, read it, type in every example, run it, bend it, break it, fix it until you understand it completely, then do every chapter exercise. Reading along will not give you a thorough understanding.

I hear you on that . . . . I am currently working through a transcender practice
test for the first Java 7 exam, and it is no walk in the park, if you do no coding, your
chances of passing are about that of a snowball in hell. I'll check into Dietel,
I've read some of their other books.

This is a great topic for me. Network interface built in a computer or added on as expansion as into the slots, are the physical parts to handle. But say in Wi-Fi network, each file contributing to the network must run at impressive accuracy for the whole network to run. There are many examples already given about File IO and anyone can use it and compile it and store it on their own and the other parties system. I am reading a book by Jackie Barker, phd in computer science, Beginning Java Objects. Excellent way to read is using UML, and to figure out where things are.
