paradigms

问题 This question already has answers here : What are the most important programming languages to know for concepts? [closed] (25 answers) Closed 5 years ago . I've been working as a developer for the past 4 years, with the 4 years previous to that studying software development in college. In my 4 years in the industry I've done some work in VB6 (which was a joke), but most of it has been in C#/ASP.NET. During this time, I've moved from an "object-aware" procedural paradigm to an object-oriented

问题 I'm mostly convinced of the benefits of unit testing, and I would like to start applying the concept to a large existing codebase written in PHP. Less than 10% of this code is object-oriented. I've looked at several unit testing frameworks (PHPUnit, SimpleTest, and phpt). However, I haven't found examples for any of these that test procedural code. What's the best framework for my situation and are there any examples of unit testing PHP using non-OOP code? 回答1: You can unit-test procedural

问题 In my Android Studio project there are two android modules "mobile" and "wear", these seem to be the views and controllers for the types of android devices that will be able to run this application I expect them to share some logic, such as the model files and POJOs so where should that be stored? I expect the "mobile" module to do a lot more heavy lifting than the "wear" module, but should I put the model objects in that module, or should I make a new third module that they can both use? (or

问题 I am trying to evolve my understanding of side effects and how they should be controlled and applied. In the following List of flights, I want to set a property of each flight satisfying a conditions: IEnumerable<FlightResults> fResults = getResultsFromProvider(); //Set all non-stop flights description fResults.Where(flight => flight.NonStop) .Select(flight => flight.Description = "Fly Direct!"); In this expression, I have a side effect on my list. From my limited knowledge I know for ex.

I know a lot of Java people have started looking at Scala since it runs on the JVM, and a lot of people in the Microsoft world are

问题 I have heard this time and again, and I am trying to understand and validate the idea that FP and OO are orthogonal. First of all, what does it mean for 2 concepts to be orthogonal? FP encourages immutability and purity as much as possible, while OO seems built for state and mutation – a slightly organized version of imperative programming? I realize that objects can be immutable, but OO seems to imply state/change to me. They seem like opposites. How does that affect their orthogonality? A

问题 I know this question is not really important.. however I've been wondering: Which of the following IF statements is the best and fastest to use? <?php $variable = true; if($variable === true) { //Something } if($variable) { // Something } ?> I know === is to match exactly the boolean value. However is there really any improvement? 回答1: Using if ($var === true) or if ($var) is not a question of style but a question of correctness. Because if ($var) is the same as if ($var == true) . And ==

问题 I use Spring MVC and a regular JDBC. I've just learned that I should separate business process into layers which are presentation layer, controller layer, service layer, and repository/DAO layer. Now suppose that I have an Entity called Person that can have multiple Jobs . Job itself is another entity which have its own properties. From what I gathered, the repository layer only manages one entity. Now I have one entity that contains another entity. Where do I "join" them? The service layer?
