. 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
Is there byte data type in C++? - Stack Overflow A byte is certainly not defined to be 8 bits, regardless of the fact that 8 bit bytes are predominant That's why we have CHAR_BIT I have worked on more than one embedded system where bytes are not 8 bits in length A char is defined to have a size of 1, so yes, a char is always a byte
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
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
math - Converting bytes to megabytes - Stack Overflow I've seen three ways of doing conversion from bytes to megabytes: megabytes=bytes 1000000 megabytes=bytes 1024 1024 megabytes=bytes 1024 1000 Ok, I think #3 is totally wrong but I have seen it I
What are bitwise shift (bit-shift) operators and how do they work? Basically, Bitwise operators can be applied to the integer types: long, int, short, char and byte Bitwise Shift Operators They are classified into two categories left shift and the right shift Left Shift (<<): The left shift operator, shifts all of the bits in value to the left a specified number of times Syntax: value << num
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?
c# - Byte [] to ASCII - Stack Overflow I received the contents of a text file returned in binary values: Byte[] buf = new Byte[size]; stream = File InputStream; stream Read(buf, 0, size); How can I convert this to ASCII?
