This article focuses on "what are the advantages of VB object-oriented". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what are the advantages of VB object-oriented"?

The term object-oriented is familiar to programmers engaged in development, and it best embodies the meaning of the word object-oriented in JAVA. In our new version of Visual Basic 7, or Visual Basic.NET, it has all the features of an object-oriented language. Even from an old vb programmer's point of view, the idea of an object is not entirely new, but code should be written in an object-oriented way as much as possible.

If you ask a master of object-oriented programming what is an object-oriented programming language? Then you may hear several absolutely indispensable words, such as class, interface, message concealment, encapsulation, inheritance, polymorphism, and so on. As a topic, an object-oriented language is not a language that can be mastered in a day or two or in a single speech. To master the object-oriented programming language, you need to do a lot of practice while mastering the theory.

Advantages of object-oriented programming in VB basic course

Are you surprised that modern programming languages are so inclined to object-oriented programming? There are several reasons why C++, as an extension of c, developed to support object-oriented programming technology, and java, the planet's programming language, is also an object-oriented programming language, and then, indeed, vb became a complete object-oriented programming language when it developed into vb.NET. There are several good reasons for this shift. Object-oriented programming has several advantages, such as easy code maintenance, good expansibility and code reuse technology. These advantages are not available in process programming. Let's talk about these advantages of object-oriented technology:

1. Easy to maintain: modularity is inherent in object-oriented programming. Entities are represented as classes that have the same function as classes in a namespace. You can add a class to a namespace without affecting other members of the namespace.

two。 Extensibility: object-oriented programming supports extensibility. If you have a class with some function, you can quickly extend the class and create another class with extended functionality.

3. Code reuse: since the functionality is compressed into a class and the class exists as a separate entity, it becomes very easy to provide a class library. The fact is that any .NET Framework programmer can use the .NET Framework class library.

Introduction to object-oriented classes in the basic course of VB

Class: class is the main focus in object-oriented programming technology. in short, a class is a data type that provides functionality. Declare a class to use the keyword class in VB.NET. For example, a class called employee is declared in list1.

Listing 1:Employee class Class Employee End Class

This is a very simple class. Note the naming rules for classes recommended by Microsoft to use Pascal. This means that the letters of the class name must be capitalized, and the first letter of subsequent concurrent conjunctions must be capitalized. A good class name should be GeneralManager,SmallDictionary StringUtil like this.

Class members: a class has members such as fields, attributes, subroutines, and functions. For example, there is a subroutine called work in the employee class in list2.

Listing 2: Class Employee Public Sub Work ()'Do something here End Sub End Class

Subroutines and functions are also called methods, and the naming of methods also follows the Pascal naming method.

The other class member type is the domain, and the naming rules of the domain follow the camel-case rule. For example, a good domain is named like salary and quarterlyBonus. In list3, we add two fields, salary and quarterlyBonus, to the Employee class.

Class Employee Dim salary As Decimal = 40000 Dim yearlyBonus As Decimal = 4000 Public Sub PrintSalary () 'print the salary to the Console System.Console.Write (salary) End Sub End Class here, I believe you have a deeper understanding of "what are the advantages of VB object-oriented".
