Object-Oriented Programming (OOP)

Classes and objects


Object-Oriented Programming (OOP) is an import feature in VB.NET. Once we talk about OOP, We always focus on classes and objects. A class is a template that can be used to create an object. Therefore, object is the instance of the class.

Creating a class


To create a class, you must use class keyword followed by the name of the class.
Example:
Class Student

End Class


A class can have two types of members-private and public members. Private member can’t be accessed by the code outside the class. In contrast, public member can be access by the code outside the class. To declare a private member, you can use private keyword and to declare a public member, you can use public keyword. Variables declared without private or public keyword are private members.

Example:


Class Student
 
        Private stnumber As Integer
        Private stname As String
        Private stsex As String
        Public sub setnumber
        End sub
 
End class
