head first object oriented analysis and design

describes how to implement the "open-closed" principle in the object-oriented design. (1) interface-oriented programmingInterface-oriented programming has the following advantages:A. reduce coupling between various parts of the program and make it possible to swap program m

　　Why Study Design Patterns:1, more in-depth understanding of object-oriented thinking2, is conducive to the development of a strong extension of things　　What is a design pattern: a typical solution for a typical scenario that often occurs is the design pattern. For example,

1. What is the open/closed principle?The "Open-Close" principle means that software entities should be open to scalability and closed to modifications. That is, the software entity should be extended without modification. This principle actually sets a goal for the software design. We know that software design should fully consider the maintainability of the software, that is, when the demand changes, the s

function of the system, function by the action of interaction, complete the action of nature is the object. So the outline design design is obvious: The system is divided into functional modules according to the result of requirements analysis, the module may be a class, or it may be a subsystem composed of multiple c

The design principle is a guiding and abstract concept. The design mode is a good practical experience to achieve the design principles. After a while of object-oriented programming. The first thing to learn is the design model.

the Internet, I find that there is less information in this regard, and the program design and implementation are relatively simple. Due to the lack of good design concepts, this results in poor program reusability. So in the Process of program design and implementation, I introduced the idea of Object-

Go [like I did!], but the official docs avoid them like The plague. "-Rodrigo Moraes via go+ "Seconding +rodrigo Moraes here, excellent stuff. I think this would has accelerated my own learning curve, where I ' ve kept looking for classical OO approaches. Thanks for the writeup. "-Levi Cook via go+ and Twitter "Great article, really enjoyed it! Well structured and example code seems to is good. Would be going over this again tomorrow and adding some of the tricks I wasn ' t aware of to my t

The content of this section, programming paradigmProgramming refers to writing programs, knocking code, refers to the programmer with specific syntax, data structures and algorithms written code, the purpose is to tell the computer how to perform the task.The two most common genres in the programming world are: process-oriented and object-oriented. "Kungfu school

Object-oriented software development methods include: A, object-oriented analysis (OOA) B, object-oriented design (OOD) C,

The design is the software realization based on the analysis model, divides into the system design and the detailed design two important stages, occupies the modularization, the coupling degree and the cohesion, the reusability principle. Software architecture is the key to the success or failure of a system, including

Three basic elements of object-oriented architecture: encapsulation, inheritance, and Polymorphism Five basic object-oriented design principles: Single-Resposibility Principle) Its core idea is: A class. It is best to do only one thing and only one change that causes it. The

Legend has it that object-oriented development patterns were first created by lazy programmers. Development so far, people from the initial hot loyalty to discuss whether a certain language is enough object-oriented to now start a broader focus on object-

Seven Principles of object-oriented design and seven Today we will talk about seven principles, namely: single responsibility, Lishi replacement, dimit law, dependency reversal, interface isolation, synthesis/aggregation principle, and openness-closure. 1. Open and Close principles(Open-Closed Principle, OCP) Definition:The software entity shall be open to extens

It is best to initialize the initial value list, and if the function body is initialized, the data member has completed the default initialization
