Question

Ok, so I have searched and searched and nothing worked…
I have this array of int, each int occupies only the low order byte. For instance, I have

data[0] = Ox52
data[1] = Oxe4
data[2] = Ox18
data[3] = Oxcb

I want that the standard output contains exactly those bytes (or in other words, if I write this in a file and I examine the file with a Hex editor, I should see):

52e418cb

How can I do that?

Thank you for your help

Answer 1

The following seems to work fine. I’m using the OutputStream.write(int) method.

int[] ints = new int[] { 0x52, 0xe4, 0x18, 0xcb };
FileOutputStream os = new FileOutputStream(new File("/tmp/x"));
for (int i : ints) {
    os.write(i);
}
os.close();

Results:
