functions, the abstract class is named abstract class, without the concept of pure, but invented a kind of called interface interface to replace the pure virtual class. The difference between interface and abstract class is similar to the difference between a generic abstract class and a pure virtual class in C + +.Abstract classes can only be used as base class

In the Java C/S software development, docking a number of third-party provided web interface. The way you use the interface is not as difficult as you might think.For example, if the provided interface is a get form, the address is output directly on the Web page, and the pa

Inheriting "base class" and inheriting "interface" can implement some same functions, but some functions that can be accomplished by some interfaces are only used by the base class.1. An interface is used to describe a common method/public property of a set of classes. It does not implement any method or property, just tells the class that inherits it"At least" to achieve what

Park,unpark,ord These 3 functions, in our work, they are not much estimated. In my most recent job, because communication requires a binary stream, the interface is received in PHP. At that time, a lot of information was consulted. Because they are less used, and few friends use them in their work. At work, I've come to understand that Park,unpark,ord is powerful for binary byte processing. Let me introduce them each. Introduction to the use of Park,

It can also be see
