OutputStream question

[Kasey Tritt]

Come across this question in an exam, anyone knows the answer?
If write(0x01234567) is called on an instance of OutputStream, what will be written to the destination of the stream? Select one write answer.
(a) The bytes 0x01, 0x23, 0x34, 0x45 and 0x67, in that order.
(b) The bytes 0x67, 0x45, 0x34, 0x23 and 0x02, in that order.
(c) The byte 0x01
(d) The byte 0x67
(e) None of the above
If the answer is none of the above, how does the write method write to the destination of the stream? Thanks.

Kasey,
Try the following code:

import java.io.*;
public class Test {
    public static void main (String[] args) {
try {
    FileOutputStream fos = new FileOutputStream ("out");
    fos.write (0x01234567);
    fos.close();
}
catch (IOException e) {}
    }
}

If you are in a linux environment, go to the shell an type "od -t x1 out", this will produce the following output:
0000000 67
0000001
That is to say, as expected the answer is "(d) the byte 0x67", because the write(int) method of the OutputStream class only writes to the underlying stream the lower byte of the input integer.
Hope this helps
