First, what is the dependency inversion principle A statement:Abstraction should not depend on detail; the details should depend on abstraction. Another statement:To program for an interface, do not program for implementation. Programming for interfaces means that you should use Java interfaces and abstract Java classes for variable type declarations, parameter type declarations, return type declarations of methods, and conversion of data types. Do no

Problem Description the inversion number of a given number sequence A1, A2, ..., the number of pairs (AI, AJ) that s Atisfy i For a given sequence of numbers a1, A2, ..., an, if we move the first m >= 0 numbers to the end of the seqence, we'll Obtain another sequence. There is totally n such sequences as the following: A1, A2, ..., An-1, an (where m = 0-the initial seqence)A2, A3, ..., an, A1 (where m = 1)A3, A4, ..., an, A1, A2 (where m = 2)...An, A

This describes how string inversion is implemented in Java in 5. One, array implementation string inversion Array implements string inversion public string Reversebyarray () { if (str = NULL | | str.length () = 1) {return null; } char[] ch = str.tochararray ();//string converted to character array for (int i = 0; i Second, s

First of all rely on injection and control inversion is said to be the same thing, is a design pattern, this design pattern to reduce the coupling between the program, I learned a bit, see TP official website has no relevant articles, write this my book introduce this design mode, hope to contribute some power to TP community.First of all, do not investigate the definition of the design pattern, otherwise you will be said Foggy, the author is deeply a

In the course of doing the project, we encountered the problem of finding polynomial, and used the method of seeking inverse. Matrix inversion generally uses a simple algorithm, there are fast algorithms such as the full selection of the main element Gauss-Jordan elimination method, but this program mainly wrote a simple matrix inverse algorithm definition method of the adjoint matrix inverse formula is as follows, where a reversible:, where the adjoi

There are several implementations for using the Java string inversion: Using the reverse function in the StringBuilder class; Using recursion, the first character of a string is placed after a substring other than the first character, and then the substring is called recursively; Use character arrays to do reverse; public class Reverse {public static string reverse1 (String str) {if (str = = NULL | | str.length () Java implementa

Role: It guides us in how to properly resolve dependencies between modules, and it is also the core principle of framework design. The essence of the dependency inversion principle is to require the relationship between classes to be based on an abstract interface. Robert Martin describes in this way the dependency inversion principle [Martin 1996]: The traditional strategy is to "divide and conquer" the

We call its center as the center of the inversion, the radius is called the inverse radius. For any tw

Six principles of design patterns (3) -- six principles of dependency inversion and Design Patterns Definition: High-level modules should not depend on low-level modules. Both of them should depend on abstract interfaces. Abstract interfaces should not depend on specific implementations. The specific implementation depends on the abstract interface.
