Object-Oriented Programming (OOP)

Create objects

To access public members of the class, you must create its object. The object can be created by using the New keyword.


Example:
Dim stu As New Student


Accessing a class’s public members through objects


To access public members of a class, you must write its name of object followed by dot sign(.) and the names of its members.


Example:
Module Module1
 
    Sub Main()
        Dim st As New Student 'create object
        st.setnumber()' accessing members
        st.getnumber()
        Console.ReadLine()
    End Sub
 
    Class Student
        Private stnumber As Integer
        Private stname As String
        Private stsex As String
        Public Sub setnumber()
            Console.WriteLine("Enter student's number:")
            stnumber = CInt(Console.ReadLine)
        End Sub
 
        Public Sub getnumber()
            Console.WriteLine("Student's number is:" & stnumber)
 
        End Sub
    End Class
 
 
End Module
