Question

I am currently using Java to communicate with device through Serial communication. I have to send packet in byte array. I did the following :

    byte[] packet = new byte[3];
    packet[0] = 'C'; //char form
    packet[1] = 'C'; //char form
    packet[2] = '2'; //char form

Is there any difference from initialize in this way :

    byte[] packet = new byte[3];
    packet[0] = 0x43; //hex form
    packet[1] = 0x43; //hex form
    packet[2] = 0x32; //hex form

The value should be the same, right?

Answer 1

Yes, they are absolutely the same. Both get converted to an int with the same value.
