Read a binary file in Scala [duplicate]

Question

I have some binary files which are written by a Java application in the following way:

DataOutputStream dos = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(complete_path_to_file)));

dos.writeInt(aInteger);
dos.writeLong(aLong);
dos.writeFloat(aFloat);

dos.close();

Now, I'd like to read this kind files in a Scala framework but I really don't have any ideas about how to do that.

Could you help me?

Why don't you read them in exactly the same way you will do in java? (with DataInputStream and such stuff?) — om-nom-nom

Yes I could, but I was wondering whether it exists a Scala-idiomatic way to do that — Aslan986

Reading it using the same classes and methods you'd use in Java is probably going to be the most error-free, as you have a direct correspondence between read and write.

You can also use Scala I/O, which is the best library for file I/O for Scala -- and a possible addition to the standard library in the future.

Then there's sbinary, where less concern is given to I/O itself, and more concern is given to describing the binary record.
