. net - What is a byte [] array? - Stack Overflow 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
How do I initialize a byte array in Java? - Stack Overflow 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"
java - What do we mean by Byte array? - Stack Overflow 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
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
Byte Array and Int conversion in Java - Stack Overflow encodedValue[1] = (byte) (value >> Byte SIZE); encodedValue[0] = (byte) value; return encodedValue; } Just reverse the byte array index to count from zero to three to create a Big Endian version of this code Notes: In Java 8 you can also make use of the Integer BYTES constant, which is more succinct than Integer SIZE Byte SIZE
Why is the range of bytes -128 to 127 in Java? - Stack Overflow 0 Without getting into two's complement: 2^8 (since a byte is 8 digits and can have 1 of 2 values) = 256, so the most individual values a byte can represent is 256 so, representing the numbers -128 to -1 is half our range I believe the question here is why is the max positive value 127 rather than 128
c# - Why does byte + byte = int? - Stack Overflow byte z = (byte)(x + y); this works What I am wondering is why? Is it architectural? Philosophical? We have: int + int = int 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 < 8) and storing the intermediate results in a large array
