VB.Net program of constructor overloading

Write a VB.Net program of constructor overloading

Here, to initialize a data member, we will create a Sample class that contains the default and parameterized constructor.

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

'VB.net program to demonstrate the constructor overloading.

Module Module1
    Class Sample
        Private num As Integer
        Public Sub New()
            Console.WriteLine("Default or no argument constructor called to initialize data members")
            num = 10
        End Sub
        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 obj1 As New Sample()
        Dim obj2 As New Sample(20)
        obj1.Print()
        obj2.Print()
    End Sub
End Module
	

We have built a Module1 module in the program above. Here, a sample class containing a data member num has been created. No argument, parameterized constructor, and a Print() method are found in the Sample class.

Initialized data members are used for all constructors, and the Print() method is used to print data member values on the console screen.

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