VB.Net program to overload less than (<) and greater than (>) operator

By Nidhi Last Updated : November 15, 2024

Overloading less than (<) and greater than (>) operator in VB.Net

Here, we will overload less than (<) and greater than (>) operators using the shared operator method, which is used to perform comparations on the object of the class.

Program/Source Code:

The source code to overload less than (<) and greater than (>) operator is given below. The given program is compiled and executed successfully.

VB.Net code to overload less than (<) and greater than (>) operator

'VB.net program to overload less than (<) 
'and greater than (>) operator.

Class Sample
    Dim num As Integer
    Sub SetValues(ByVal n As Integer)
        num = n
    End Sub

    Public Shared Operator <(ByVal S1 As Sample, ByVal S2 As Sample) As Boolean
        If (S1.num < S2.num) Then
            Return True
        Else
            Return False
        End If
    End Operator
    Public Shared Operator >(ByVal S1 As Sample, ByVal S2 As Sample) As Boolean
        If (S1.num > S2.num) Then
            Return True
        Else
            Return False
        End If
    End Operator

    Sub PrintValues()
        Console.WriteLine("Num: {0}", num)
    End Sub

End Class

Module Module1
    Sub Main()
        Dim obj1 As New Sample()
        Dim obj2 As New Sample()

        obj1.SetValues(10)
        obj2.SetValues(20)

        If (obj1 < obj2) Then
            Console.WriteLine("Obj1 is less than Obj2")
        Else
            Console.WriteLine("Obj2 is less than Obj1")
        End If

        obj1.SetValues(30)
        obj2.SetValues(20)

        If (obj1 > obj2) Then
            Console.WriteLine("Obj1 is greater than Obj2")
        Else
            Console.WriteLine("Obj2 is greater than Obj1")
        End If
    End Sub
End Module

Output:

Obj1 is less than Obj2
Obj1 is greater than Obj2

Explanation:

In the above program, we created a class Sample that contains two methods SetValues(), PrintValues() to set and print the values of data members of the class. Here, we also implemented methods to overload less than (<) and greater than (>) the operator, then we can perform comparation on objects.

After that, we created a module Module1 that contains the Main() method, the Main() method is the entry point for the program. And, we created the two objects of Sample class and set the value of data member using SetValues() method and then perform comparation on objects. After that appropriate message will be printed on the console screen.
