For obvious reasons, you cannot power off a device programmatically.

So far It's only possible with rooted device or app should be signed with the system firmware signing key.

try {
    Process proc = Runtime.getRuntime()
                    .exec(new String[]{ "su", "-c", "reboot -p" });
    proc.waitFor();
} catch (Exception ex) {
    ex.printStackTrace();
}
