Byte

Understanding byte requires examining multiple perspectives and considerations. How do I initialize a byte array in Java? 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

Can endianness refer to the order of bits in a byte?. 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". Moreover, how to convert byte[] to Byte[] and the other way around?. How to convert byte[] to Byte[] and also Byte[] to byte[], in the case of not using any 3rd party library?

Is there a way to do it fast just using the standard library? Additionally, c# - byte [] to hex string - Stack Overflow. How do I convert a byte[] to a string? Every time I attempt it, I get System.Byte[] instead of the value. Also, how do I get the value in Hex instead of a decimal?

java - What do we mean by Byte array? 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.

Another key aspect involves, for large amounts of binary data, it would be better to use a streaming data type if your language supports it. Java Byte Array to String to Byte Array - Stack Overflow. To convert your response string back to the original byte array, you have to use split(",") or something and convert it into a collection and then convert each individual item in there to a byte to recreate your byte array. What's the difference between a word and byte? The byte is the smallest addressable unit for a CPU.

If you want to set/clear single bits, you first need to fetch the corresponding byte from memory, mess with the bits and then write the byte back to memory. c# - Why does byte + byte = int? Similarly, long + long = long float + float = float double + double = double So why not: byte + byte = byte short + short = short? A bit of background: I am performing a long list of calculations on "small numbers" (i.e. It's important to note that, < 8) and storing the intermediate results in a large array.

From another angle, using a byte array (instead of an int array) is faster (because of cache hits). java - Byte [] to InputStream or OutputStream - Stack Overflow.
