Sending files in java

[imported_nautique]

Does java provide a way to send entire files as bytes at once or do you have to read each line and write each line individually?

You could have a look at PipedReader and PipedWriter. PipedInputStream and PipedOutputStream have a warning about deadlock safety but the Reader and Writer don't; I'm not sure why they'd be any different, but I guess they're safe.

You can use FileInputStream to read a file in by bytes...

what do you mean by "send"?

Keep reading bytes from the file until EOF. Send these bytes to the other computer.

And if you don't know how to extract bytes from a file, you haven't read the API closely enough; it's the most elementary operation for a Stream.

First, you learn JNI. Then you wrap a call to sendfile.

Wtf? So basically you're suggesting something that's more work to do, slower, less secure and less portable?
