What is the real OOP?

iheshi 2004-03-10 09:18:30

看了一段时间的JAVA了（Think in Java）。语法、一些常识性的东西已经了解了。
自己也写了一些小的练习的小程序，可是到了现在，我还是没有真正了解OOP的思想。

OOP的思想就是：
世间万物都是对象。Reference是控制对象的钥匙。然后是堆和栈。

那么，再进一层呢？

Programming in the modular manner is always encouraged for bigger systems―it is easier to achieve scalability with modular programming. Even JavaScript developers are now interested in building programs in a modular pattern. Modules help people who aren’t yet familiar with code to find what they are looking for and also makes it easier for programmers to keep things that are related close together. Designing and implementing applications in a modular manner is highly encouraged and desirable in both simple and enterprise level applications. This book covers some real-life examples of modules and how we can translate that into our world of programming and application design. After getting an overview of JavaScript object-oriented programming (OOP) concepts and their practical usage, you should be able to write your own object definitions using the module pattern. You will then learn to design and augment modules and will explore the concepts of cloning, inheritance, sub-modules, and code extensibility. You will also learn about SandBoxing, application design, and architecture based on modular design concepts. Become familiar with AMD and CommonJS utilities. By the end of the book, you will be able to build spectacular modular applications in JavaScript. What You Will Learn Understand the important concepts of OOP in JavaScript, such as scope, objects, inheritance, event delegation, and more Find out how the module design pattern is used in OOP in JavaScript Design and augment modules using both tight augmentation and loose augmentation Extend the capabilities of modules by creating sub-modules using techniques such as cloning and inheritance Move from isolated module pieces to a cohesive, well integrated application modules that can interact and work together without being tightly coupled See how SandBoxing is used to create a medium for all the modules to talk to each other as well as to the core Use the concepts of modular application design to handle dependencies and load modules asynchronously Become familiar with AMD and CommonJS utilities and discover what the future of JavaScript holds for modular programming and architecture

Experiment 1 The QuickSort Algorithm 1.Introduction to the quicksort algorithm In order to sort the input data sequence S, we can do like below: 1)Select one number q and then divide the sequence S into three sub-suquences: S1 in which all of elements are less than q, S2 in which all of elements are equal to q, and S3 in which all of elements are larger than q; 2)Then to sort S1 and S3 with the same algorithm using recursive call itself. 2. Experimental Purposes （1）Learn the sorting algorithms. （2）Understand the difference between the quicksort algorithm and other sorting algorithms, such as: insertion sorting algorithm, straight selection algorithm, etc.. （3）Simulate these algorithms using computer with high-level languages. （4）Solve some sorting problem with different sort algorithms. 3. Abstract of Experiment contents Use QuickSort algorithm to sort the array S that has n elements and constructed by the random() function. To compare the result with ones solved by other sorting algorithms, such as Straight selection sort, insert sort, etc., and understand the difference among them and know how to select some better sorting algorithm while solving some sorting problem. 4. Experimental Requirements 1)The template should be used for all kinds of data type, such as: integer, real, double, etc. in the program; 2)Programs should be made by Object-Oriented Programming (OOP) method; 3)The results should be compared with ones of other algorithms, such as: Straight selection sort, insert sort, Heapsort, etc., and draw the graph to find their differences. Figure 1 The difference between quicksort and insertion sort 4)Write down the report in which there should be the execution results of the program. 5. Example code with C++ ………. void myquicksort(int* A, int l,int r) { if(l>=r) return ; int i=l,j=r; int temp; //Use it to divide A into S1, S2,and S3 ……. //Partition S into S1, S2 and S3 here ……. myquicksort(A,l,i-1); //recursive call for the left part

Object Oriented Programming with Swift 2 by Gaston C. Hillar 2016 | ISBN: 1785885693 | English | 332 pages Get to grips with object-oriented programming in Swift to efficiently build powerful real-world applications About This Book Leverage the most efficient object-oriented design patterns in your Swift applications Write robust, safer, and better code using the blueprints that generate objects Build a platform with object-oriented code by using real-world elements and represent them in your app Who This Book Is For If you are an iOS developer who has a basic idea of object-oriented programming and want to incorporate its concepts with Swift to optimize your application's code and create reusable and easily to understand building blocks, then this book is for you. This is a very useful resource for developers who want to shift from Objective C, C#, Java, Python, JavaScript, or other object-oriented languages to Swift What You Will Learn Build solid, stable, and reliable applications using Swift Work with encapsulation, abstraction, and polymorphism using Swift 2.0 Customize constructors and destructors based on your needs Develop Swift 2.0 with classes, instances, properties, and methods Take advantage of generic code to maximize code reuse and generalize behaviors Use state of inheritance, specialization, and the possibility to overload members Write high quality object-oriented code to build apps for iOS or Mac OS X In Detail Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects; these are data structures that contain data in the form of fields, often known as attributes and code. Objects are everywhere, and so it is very important to recognize elements, known as objects, from real-world situations and know how they can easily be translated into object-oriented code. Object-Oriented Programming with Swift is an easy-to-follow guide packed full of hands-on examples of solutions to common problems encountered with object-oriented code in Swift. It starts by helping you to recognize objects using real-life scenarios and demonstrates how working with them makes it simpler to write code that is easy to understand and reuse. You will learn to protect and hide data with the data encapsulation features of Swift. Then, you will explore how to maximize code reuse by writing code capable of working with objects of different types. After that, you'll discover the power of parametric polymorphism and will combine generic code with inheritance and multiple inheritance. Later, you move on to refactoring your existing code and organizing your source for easy maintenance and extensions. By the end of the book, you will be able to create better, stronger, and more reusable code, which will help you build better applications. Style and approach This simple guide is packed with practical examples of solutions to common problems. Each chapter includes exercises and the possibility for you to test your progress by answering questions. Nitroflare.com
