Since the project needs to compress an ID (number) into as short a string as possible, I haven't found a suitable one on the internet for a long time.Write one yourself.There is a need to refer to, but also as some of their own accumulation bar!The code is as follows:Java code

One: unsafe (non-reentrant) inet_xxx () function FamilySince computer-understood IP is stored in binary form, the conversion of string IP and binary IP is often required in network programming, and the Linux system has a set of functions to be used for network address translation, as follows: #include some of the above functions are defective, for example:T
To convert a file to a binary method:
/// /// Convert the file to binary/// /// /// Public static byte [] converttobinary (string path){Filestream stream = new fileinfo (PATH). openread ();Byte [] buffer = new byte [stream. Length];Stream. Read (buffer, 0, convert. toint32 (stream. Length ));Return buffer;}
To convert binary data to a file:
Using system. IO;

In fact, it is estimated that there is no such requirement, just write.
Can we convert it from binary to hexadecimal directly? The most direct way is through the displacement operation, that is, every four bits correspond to a hexadecimal,
If there is a basic binary type in Java, binary Bi = new binary (11010101); in t

Today, when I was reading C language code conversion, since I had forgotten the negative Binary Expression, I checked the online information and they said it was a p! Mistaken! I have discussed it with you and posted it as I have forgotten it here:
Suppose there is a number of the int type with the value of 5, then we know that it is represented in the computer:
00000000 00000000 00000000 00000101
5 is conv
NPY and FFTTime limit:2000/1000 MS (java/others) Memory limit:32768/32768 K (java/others)Total submission (s): 799 Accepted Submission (s): 492Problem Descriptiona Boy named NPY are learning FFT algorithm now. In this algorithm,he needs to does an operation called "reverse".For example,if the given number are 10.Its binary representaion is 1010.After reversing,the binary number would be 0101.And Then we sho

In the recent use of remote network modules,The socket to be used to send data, the remote module instruction is 16 binary.The official demo is a bit cumbersome. Not easy for beginners to use.The following conversion functions are much easier for beginners to use.//16 binary string The byte array is formatted as String sendMessage = "The FF-XX"; Private Static byte[] Hexstrtobyte (stringhexstring) {h
Problem:Conversion between characters in C can be in Char A=char (b+5), but in Java it is useless, here is a conversion method: int C=b+5;char A=char (c);string strings, upside down:Stringbffer str=new StringBuffer (s);S=str.reverse (). toString ();In the test added some output statements, and some small changes, in the output forget to change back, leading to not pass, please note!!!Binary conversionTime

Conversion of binary and Gray Codes Using Tilde
Gray Code features: There is only one difference between two adjacent code groups.
Common binary codes and gray codes can be converted to each other. The following is a brief introduction.
