. 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
Is a byte always 8 bits? - Stack Overflow A byte is a software unit representing an amount of data, while a word is more tied to the processor memory architecture and represents work units (registers) in the processor and the addressable units in memory Nowadays though, a byte is always considered to be 8 bits, and words are a multiple of that
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?
Converting from byte to int in Java - Stack Overflow Java's byte primitive only supports values between -128 to 127 If someone tries to stuff an unsigned value (like 0xC8) into that, it can roll over with a bunch of leading ones (due to the twos complement notation)
Convert byte to string in Java - Stack Overflow Because gustafc's answer has a very important point: String (byte []) constructor uses the System default encoding to convert the byte array into String characters One should not assume that a 0x63 byte value is mapped to the letter 'c' For example, in UTF-16 the letter 'c' is represented by 2 encoding bytes, not one
