From http://www.vaikan.com/program-to-an-interface-fool/For ' interface ' programming, not for ' implementation '.What does that mean? First we need to understand what is ' interface ' and what is ' implementation '. In short, an interface is a collection of the series of methods that we want to invoke, with objects that respond to these method calls.An implementation is where code and logic are stored for the interface.Essentially, this principle adv

Explore UDP socket programming and udp socket programming UDP and TCP are in the same layer network model, that is, the transport layer. There are many applications based on the two. Common TCP-based applications include HTTP and Telnet, UDP-based DNS, NFS, and SNMP are available. UDP is a connectionless and unreliable data protocol service, while TCP provides stream-oriented and reliable data services. Not

As a popular course in primary and secondary schools, scratch is different from the traditional character code. There is no English threshold for Graphic programming. By dragging blocks, children can intuitively understand the operating principle behind the code, without knowing it, you can master programming algorithms. Through simulated cartoon project-based teaching such as animations that students love,

At the outset, let's ask a few questions and believe it's a program that knows:For example, what does 0, 1 mean?For example, what does a,b,c,d,e represent?0,1 is a numeric value, a bits; ABCDE is a symbol and can be used as a variable.If you do not understand, you can continue to look at the following pseudo-code:Va= ""; VB= ""; VC= ""; VD= ""; VE= "";What do these variables mean? What is the relationship between them? These 5 variables, all of which represent the string "" AhNow, look at th

These two days the new school younger brother study sister only then began to learn the programming language, see the functions and classes when not much understand, recall the time before learning is also the case, so decided to write a most straightforward blog to help you understand what is class (class), what is Object (objects), incidentally mentioned a little function ( function). A class is an abstract concept that is an abstraction of a class

This week Rickard Oberg announced the launch of Qi4j on Oredev and declared that "the class is dead and the interface is long live." Qi4j brings a new idea for combinatorial programming, proposing that there is no longer any behavior in the class, instead, the class becomes a ' combination ' of mixed (mixins) and uses annotations in the class to define the interface. QI4J itself is a Java framework for combinatorial

process-oriented programming Process-oriented programming is a process-centric programming idea, analyzing the steps to solve the problem, and then using the function to implement these steps step by step. Process-oriented programming, data and the operation of the data is separate. Object-oriented
