Jun 26, 2012 · In Java 6, there is a method doing exactly what you want: private static final byte[] CDRIVES = javax.xml.bind.DatatypeConverter.parseHexBinary ...

Jan 19, 2010 · so you end up with a byte[]. this could represent any kind of data which may need special types of conversions (character, encrypted, etc). let's pretend you want to write this data as is to a file. firstly you could create a ByteArrayInputStream which is basically a mechanism to supply the bytes to something in sequence.

Mar 8, 2009 · 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?

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 …

Mar 21, 2011 · There is no mention of a literal suffix on the MSDN reference for Byte as well as in the C# 4.0 Language Specification. The only literal suffixes in C# are for integer and real numbers as follows: u = uint l = long ul = ulong f = float m = decimal d = double If you want to use var, you can always cast the byte as in var y = (byte) 5

Sep 7, 2012 · Moreover, a byte primitive according to the Java's spec represents a value between −128 and 127. For instance, if a byte is cast to an int Java will interpret the first bit as the sign and use sign extension. Then, how to convert a byte greater than 127 to its binary string representation ??

namespace std { // define std::byte enum class byte : unsigned char {}; }; This if your C++ version does not have std::byte will define a byte type in namespace std. Normally you don't want to add things to std, but in this case it is a standard thing that is missing. std::byte from the STL does much more operations.

Jan 23, 2014 · I byte per character does not allow for this and in use it is larger often 4 bytes per possible character for all encodings, not just ASCII. The final character may only need a byte to function or be represented on screen, but requires 4 bytes to be located in the rather vast global encoding "works".

Mar 4, 2011 · If you're doing a lot of this sort of thing, you can define a simple helper method byte b(int i) { return (byte) i; } somewhere and statically import it. Then you can write f(b(10)). Then you can write f(b(10)).

First, the byte is converted to an int via widening primitive conversion (§5.1.2), and then the resulting int is converted to a char by narrowing primitive conversion (§5.1.3). Note that in Java, most integer calculations are performed using 32-bit integers if the two operands are different types, unless one of them is a long .
