Therefore, I personally read the legal compilation, but I don't have to write a program. Writing a program is really not a compilation strength. You may wish to play DEBUG, sometimes CRACK has a more sense of accomplishment than a program (just like

The most widely used character set and its encoding in the current computer is by the U.S. National Standards Agency (ANSI) The developed ASCII code (AMERICAN Standard Code for Information interchange, United States Standards Information Interchange

Encryption principle: the valid password of the Access database is 13 BITs. When not encrypted, the 67th-9 bits of the database are fixed strings, and each ASCII code value is 86, FBEC37, 5D, 44, 9C, FA, C6, 5E, 28, E6, 13. During encryption, each

There are several types of escape characters in Java, which are common:Octal escape character, format: \ + 1 to 3-bit octal digits, such as \1, \20, range from/to \377, that is, the maximum value is 255.Unicode escape character, format: \u + four

1: "Byte" is byte, "bit" is bit;2:1 byte = 8 bit;Char is 2 bytes in Java. Java uses unicode,2 bytes (16 bits) to represent one character.ButString str = "compilation";byte[] bytes = Str.getbytes (); I wonder why it takes 3 bytes here?3 byte is 3*8=24

For starters, many of the commands in the compendium are too complex, often for long periods of time, to write a beautiful program that hinders our interest in learning a compilation, and many people give up. My personal view is to learn the
