Subject: Re: Byte Array for storing hexa decimal value

Hi,

There are no "hexadecimal numbers". An integer is an integer, but it can 
have different *representations* (binary, octal, hexadecimal etc.).

So you simply put the integers into an Array, and whenever you display 
them, you use the hexadecimal representation. This can be done with the 
to_s method:

91.to_s(16)

The 16 specifies the base (16 for hexadecimal, 2 for binary etc.).

By the way, I'm not even sure what you mean by "byte array". The byte 
type in Java is simply a shortened integer.
