Writing a byte to a file

suggest change

byte[] bytes = { 0x48, 0x65, 0x6c, 0x6c, 0x6f };

try(FileOutputStream stream = new FileOutputStream("Hello world.txt")) {
    stream.write(bytes);
} catch (IOException ioe) {
    // Handle I/O Exception
    ioe.printStackTrace();
}

byte[] bytes = { 0x48, 0x65, 0x6c, 0x6c, 0x6f };

FileOutputStream stream = null;
try {
    stream = new FileOutputStream("Hello world.txt");
    stream.write(bytes);
} catch (IOException ioe) {
    // Handle I/O Exception
    ioe.printStackTrace();
} finally {
    if (stream != null) {
        try {
            stream.close();
        } catch (IOException ignored) {}
    }
}

Most java.io file APIs accept both Strings and Files as arguments, so you could as well use

File file = new File("Hello world.txt");
FileOutputStream stream = new FileOutputStream(file);
