Sending 0x04 - like hexadecimal char[] data using DatagramPacket

I have a DatagramSocket and want to send char[] charData = { 0xff, 0x04, 0x02, 0xfb} data via DatagramSocket using DatagramPacket.

DatagramPacket is using byte[] as data. But I should send it like charData variable.

Any suggestions?

you could use ObjectOutputStream and ByteArrayOutputStream:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(charData);

byte[] toSend = baos.toByteArray();
oos.close();
baos.close();
int port = xxxx;
DatagramPacket p = new DatagramPacket(toSend,toSend.length,InetAddress.getByName("host"),port);
DatagramSocket s = new DatagramSocket();
s.send(p);
