The following text is from Java to javaee. During module design, a high-level abstract module is usually a business-related module. It should be reusable and independent from a lower-layer module. For example, if a lower-level module is originally a disk access mode, the high-level module is an archive backup requirement. If the High-Level module directly calls the method of the lower-level module, the dependency between the lower-level module is generated. For example, the following code: //..

Oracle inversion inversion function Oracle provides a reverse inversion function reverse, but this function cannot be grouped upside down, this article provides a function that can be grouped upside down, as follows: CREATE OR REPLACE FUNCTION reverse_f (p_str VARCHAR2, P_delimiter varchar2:= ")Return VARCHAR2 isV_return VARCHAR2 (4000);VP_STR VARCHAR2 (4000): =

Dependency-inversion principle A. High-level modules should not depend on low-level modules. Both of them should depend on abstraction. B. abstraction should not depend on details, but on abstraction. The high-level module containsProgramImportant policy selection and business model in. it is these high-level modules that make all their applications different from others. if the upper layer depends on the lower layer, the changes to the lower lay

should do the same without a doubt when designing software. Design the Framework Design Interface, design the interface, and then call the APIS or classes to implement a specific implementation, such as database read/write or socket data sending and receiving. Each place has its own opposite responsibilities and does its part. If there are APIs, it is equivalent to a large group of engineers doing both business negotiation and coding. The results are the same: chaotic. Finally, let's get down t

Numerical inversion algorithm and inversion algorithm I encountered an algorithm question during the interview today and asked to put a number upside down. At that time, I had a slight flaw in my answers on paper. I came back and made some special improvements. I have already passed the debugging, I hope to provide a little help to the interviewees in the future. The following code is attached: Public cla

String inversion and String Inversion This is a question in a java interview question on the Internet: The problem is: how to reverse a String. String str = "1234567"; int length = str. length (); int beginIndex = length-1; char [] sourceCharArray = str. toCharArray (); char [] discCharArray = new char [length]; int j = 0; for (int I = beginIndex; I> = 0; I --) {discCharArray [j] = sourceCharArray [I];

Simple question of Mobius Inversion: Mobius InversionMobius Function Here we will briefly describe the Mobius function: If d = 1, then μ (d) = 1If d = p1p2... Pr (r is a different prime number and the number of times is one) μ (d) = (-1) ^ rRemaining μ (d) = 0 GCD Question transfer: HDU-1695-GCD Evaluate the logarithm of two numbers in [1, n], [1, m] Where gcd is k Train of Thought: here we can transform the number of mutually qualitative numbers

temp->next = newlist->next newlist->next = temp temp = Temp->next return newlist 2, in-place reverse linked list. Iterate through the linked list, inserting the next node of the current list's head nodes into the next node in the header, so that it can be reversed in place. such as 1->2->3->4->5 first turn into 2->1->3->4->5, and then turn into 3->2->1->4->5 so that the last node can be reversed in place. Specifically, the code operates as follows: Reverse (NodeList list) if l

First look at an example: 1. Detailed example code for PHP control inversion (IOC) and Dependency injection (DI) Introduction: That is, if in the future development process, to the Class B or Class C modification, once the change of function, the number of function parameters, and even the entire class structure adjustment, we have to make corresponding adjustments to a class, a class of independence lost, which in the development process is very in

OrderThe first time I learned the concept of control inversion (inversion of controls) was when learning the spring framework. IOC and AOP, as the two characteristics of spring, are naturally going to learn well. and Dependency Injection (Dependency injection, short di) makes me confused for a long time, always trying not to understand the connection between them.Control reversalControl reversal as the name
