How to send byte array with processing

Question

I'm new to processing. I've made some GUI in Processing and I need to send some bytes to another MCU via Serial port to control LEDs. I need to send this code A0 0C 01 A2.

byte on[]={0xA0, 0x0C, 0x01, 0xA2}; 
port.write(on); 
//This won't compile

How I can do that?

You're on the right track, just need to use the Processing syntax (not the Arduino one) for the byte array:

byte[] on = {(byte)0xA0, (byte)0x0C, (byte)0x01, (byte)0xA2};
