Learning1. Combine OOD and OOA when learning OOP; otherwise, it is difficult to understand what object-oriented design is.2. understand UML3. Understand the design mode4. Learn about open-source projects5. When the project is large, you can use UML to draw a picture. If the problem is unclear, you must draw a picture first. When you are clear about the solution, you can write test cases first. In this way, you can also take the class structure into ac

object-oriented concept, and introduced various language-independent tokens. This method uses the object model, dynamic model, function model, and case model to model the entire system, the defined concepts and symbols can be used in the entire process of analysis, design, and implementation of software development. Software developers do not have to convert concepts and symbols at different stages of the development process. OMT-2 is particularly useful for analyzing and describing data-centri

The search process runs through the query. if the query is not specified, but starts from the index content, "Search" is a non-objective and meaningless process. the start point of the search process can only be an index.ToSee how query is used to start a query. public class BasicSe

Java is an object-oriented programming language, the Java language has encapsulation, inheritance, polymorphism, three features, which makes the Java language more powerful than other programming languages, and easier to use. The Java language, represented as a static object-oriented programming language, implements an object-oriented theory that allows programmers to perform complex programming in an elegant way of thinking.I tidy up, is probably these difficulties, first of all to organize an

25 Key learning points to be a Java guruwant to be a Java Daniel? Learn these 25 essentials. 1. You need to be proficient in object-oriented analysis and Design (ooa/ood), involving patterns (GOF,J2EEDP), and integrated patterns. You should understand UML, especially class, object, interaction, and Statediagrams. 2. You need to learn the basics of the Java language and its core class libraries (collections, serialization, streams, networking, multithr

completion of the database, Java as a mainstream programming language, with the ability to interact with the database, project development has a large number of configuration work needs to be integrated XML data to provide support, It is important to be proficient in the operation of this data.Phase IIDatabase and data access technologyIn the information today, the data has become a very important enterprise resources, data management is generally responsible for the completion of the database,

of the right;Here we are going to design patterns by abstracting the business logic that may be changing;3.1 "Model ExtensibilityIn the above introduction we probably understand the requirements, the following we want to "parentmessage" the priority attribute to judge, because these two priorities for business logic processing is different, but there may be the same logic, which is fully consistent with our OOA, The center of OOP, we can carry out a

object-oriented in Java Concept: Object-oriented original meaning is "All things are Objects" " object-oriented thinking characteristics: is a thought that is more in line with our thought habits, simplifying complex things. has transformed our character, transformed us from the executor to the leader. Object-oriented features: Package (encapsulation) Inheritance (inheritance) Polymorphic (polymorphism) Some of the professional vocabulary: Object-oriented analytic

implementation class, which produces a direct dependency on the specific implementation class. The coupling of the code becomes higher. Unity is a container, a factory of manufacturing objects, how many objects you need, and how many objects it makes. It can also manage the mapping between these abstract interfaces and the concrete implementation classes. This is what people often say about the benefits of being dependent on abstraction.In reality, there may be abstract interface Iblluserform,

basis, view of the organization granularity directly inherit user interface design, model organization granularity is based on some kind of analysis design thought (such as ooa/d) domain modeling results, The controller needs to coordinate both the view and model, but the organization and granularity of the view and model are not equal, which makes the controller face a problem of "How many domain objects to communicate and coordinate in the range of

Basic object-oriented conceptsObject-oriented includes 3 parts: Object Oriented Analysis,ooa, object-oriented design (objects oriented Design,ood), and object-oriented programming (objects oriented Program), object-oriented two key concepts are classes and objects.Class:A class is a collection of variables and methods that act on those variables.Object:An object is a product of a class that is instantiated and is an entity.Three main features of ob

Obviously, the database has degenerated into the same level as the file system in the operating system, and the era of its centrality is really over, and IBM's early open source of DB2 database has been a strong reminder to us. For Java EE Beginners, early discard the past two kinds of influence: process language programming habits and database-centric design habits, from the new object-oriented perspective (
