Help required in polymorphism

[rohan1981]

Hi, See my code below. Public Class OOPS      Public Function Check(ByVal a As Int32, ByVal b As Int32) As Int16           Return a + b      End Function      Public Function Check(ByVal a As Int16, ByVal b As Int16) As Int16           Return a - b      End Function End Class      Dim obj As New OOPS      Dim retVal As Int16      retVal = obj.Check(1, 2) Which function will be called the first one or the second one and why. Thanks in advance for your help Rohan
