21 In .NET, a byte is basically a number from 0 to 255 (the numbers that can be represented by eight bits). So, a byte array is just an array of the numbers 0 - 255. At a lower level, an array is a contiguous block of memory, and a byte array is just a representation of that memory in 8-bit chunks.
Endianness and byte order When a value larger than byte is stored or serialized into multiple bytes, the choice of the order in which the component bytes are stored is called byte order, or endian, or endianness. Historically, there have been three byte orders in use: "big-endian", "little-endian", and "PDP-endian" or "middle-endian".
I have to store some constant values (UUIDs) in byte array form in java, and I'm wondering what the best way to initialize those static arrays would be. This is how I'm currently doing it, but I feel

A byte is 8 bits (binary data). A byte array is an array of bytes (tautology FTW!). You could use a byte array to store a collection of binary data, for example, the contents of a file. The downside to this is that the entire file contents must be loaded into memory. For large amounts of binary data, it would be better to use a streaming data type if your language supports it.
