Operator Overloading Examples

Example : Operator Overloading Examples in VB .Net program to show Binary Addition(+) Operator Overloading.

Class Example

Dim num1 As Integer
Dim num2 As Integer

Sub Input(ByVal val1 As Integer, ByVal val2 As Integer)
     num1 = val1
     num2 = val2
End Sub

Public Shared Operator +(ByVal Obj4 As Example, ByVal Obj5 As Example) As Example
     Dim temp As New Example()
     temp.num1 = Obj4.num1 + Obj5.num1
     temp.num2 = Obj4.num2 + Obj5.num2
     Return (temp)
End Operator

Sub Output()
     Console.WriteLine(vbTab & “{0}”, num1)
     Console.WriteLine(vbTab & “{0}”, num2)
End Sub

End Class

Module Module1
     Sub Main()
          Dim obj1 As New Example()
          Dim obj2 As New Example()
          Dim obj3 As New Example()

          obj1.Input(100, 200)
          obj2.Input(300, 400)
          obj3 = obj1 + obj2

          Console.WriteLine(“The Value of Object1 = “)
          obj1.Output()

          Console.WriteLine(“The Value of Object2 = “)
          obj2.Output()

          Console.WriteLine(“The Value of Object3 = “)
          obj3.Output()
     End Sub
End Module

Output:

The Value of Object1 =
     100
     200
The Value of Object2 =
     300
     400
The Value of Object3 =
     400
     600

Example : Operator Overloading Examples in VB .Net program to show Binary Subtraction(-) Operator Overloading.

Class Example

Dim num1 As Integer
Dim num2 As Integer

Sub Input(ByVal val1 As Integer, ByVal val2 As Integer)
     num1 = val1
     num2 = val2
End Sub

Public Shared Operator +(ByVal Obj4 As Example, ByVal Obj5 As Example) As Example
     Dim temp As New Example()
     temp.num1 = Obj4.num1 – Obj5.num1
     temp.num2 = Obj4.num2 – Obj5.num2
     Return (temp)
End Operator

Sub Output()
     Console.WriteLine(vbTab & “{0}”, num1)
     Console.WriteLine(vbTab & “{0}”, num2)
End Sub

End Class

Module Module1
     Sub Main()
          Dim obj1 As New Example()
          Dim obj2 As New Example()
          Dim obj3 As New Example()

          obj1.Input(100, 200)
          obj2.Input(300, 400)
          obj3 = obj1 – obj2

          Console.WriteLine(“The Value of Object1 = “)
          obj1.Output()

          Console.WriteLine(“The Value of Object2 = “)
          obj2.Output()

          Console.WriteLine(“The Value of Object3 = “)
          obj3.Output()
     End Sub
End Module

Output:

The Value of Object1 =
     100
     200
The Value of Object2 =
     300
     400
The Value of Object3 =
     -200
     -200
