Need to store 16 bytes in java.Which datatype i should use and how

Question

I need to store 16 bytes in java.

How can i do the same.

Issue :

M = D || I

Here D would be 8 bytes, I would be 8 bytes and || denotes concatenation

so M will be 128 bits or 16 Byte long.

How can i store M in java datatype?

Answer 1

How about a byte array ?

byte[] data = new byte[16];
