'VB.Net program to demonstrate the copy constructor.

Module Module1
    Class Sample
        Private num As Integer

        Public Sub New()
            Console.WriteLine("Default or no argument constructor called")
        End Sub
        Public Sub New(ByVal n As Integer)
            Me.New()
            Console.WriteLine("Parameterized constructor called")
            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:

Id: 101
Name: Rohit
Id: 101
Name: Rohit

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 no argument, copy constructor, and a Print() method.

The copy constructor is used to initialize the object from other objects, and the Print() method is used to print the value of data members 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.
