VB.Net program to demonstrate the parameterized constructor

Parameterized constructor in VB.Net

Here, we will create a Sample class with a parameterized constructor; the parameterized constructor will initialize the data members of the class.

Program/Source Code:

The source code to demonstrate the parameterized constructor is given below. The given program is compiled and executed successfully.

VB.Net code to demonstrate the example of parameterized constructor

'VB.net program to demonstrate the parameterized constructor.

Module Module1
    Class Sample
        Private num As Integer

        Public Sub New(ByVal n As Integer)
            Console.WriteLine("Parameterized constructor called to initialize data members")
            num = n
        End Sub

        Public Sub Print()
            Console.WriteLine("Value of num: {0}", num)
        End Sub

    End Class
    Sub Main()
        Dim obj As New Sample(20)
        obj.Print()
    End Sub
End Module

Output:

Parameterized constructor called to initialize data members
Value of num: 20

Explanation:

In the above program, we created a module Module1. Here, we created a class Sample that contains a data member num. The Sample class contains a parameterized constructor and a Print() method.

The parameterized constructor is implemented using the New keyword, here we initialized the data member num by specified parameter. The Print() member is used to print the value of data member num on the console screen.

The Main() method is the entry point for the program, here we created an object of Sample class and then printed the value of data member num on the console screen.
