Bitwise operations in Java  Java bit operator Bitwise operators are used to operate binary bits. Java provides bitwise operators as shown below: Bitwise operator (>>,>>,&, |, ^ ,~ ), In the bitwise operator, ~ The others are binary operators. The

Objective Enum, that is, the enumeration, from the C language, C + +, Java, objective-c, Swift These languages, of course, have the corresponding enumeration type, the function may have less, but the core is a-specification of the definition of the

In the Objective-c language, Apple introduced two macros in iOS to redefine the enumeration type (that is, Ns_enum and ns_options), which is essentially the same as defining enumerated types, but in using Ns_enum for general enumerations, Ns_enumm

The magic of Python is a method that allows you to add "magic" functionality to your custom classes. In the official Python documentation, the introduction or description of these methods is not only fragmented, but also loosely structured. This

1,sort method Syntax: function sort (... args): ArraySorts the elements in an array. Flash is sorted according to Unicode values. (ASCII is a subset of Unicode.) ） By default, Array.Sort () is sorted by the instructions in the following list:Sorting

One of the advantages of using the Python magic method is that it provides an easy way to make objects behave like built-in types. This means that you can avoid performing basic operations with ugly, anti-intuitive, and nonstandard methods. In some

(This question is not difficult, but the bad habits of procrastination and fear have eaten me for more than 10 days.) Related Concepts: difference or: ^ bitwise OR 0 if the two binary digits involved in the calculation are the same; otherwise, the

Marker enumeration and bitwise operations, marker enumeration operations Notes First, define the flag enumeration: Create an IsEnums. cs class in the model folder of the project. [Flags]Public enum ABC{A = 1,B = 2,C = 4, } Then reference the model

C language-bitwise operator, C language-OperatorI. bitwise operators 1. bitwise AND :& 1> Functions * The result bit is 1 only when the corresponding two binary bits are 1. Otherwise, the result bit is 0. * Example: 10 is represented as 1010 in

Network broadcast address calculation method: (1) bitwise AND operation on the IP address and subnet mask to obtain the network address (2) "inverse" Operation on the subnet mask, then perform the bitwise OR operation with the network address to
