Program to calculate simple interest in vb.net

Vb Program to calculate simple interest. Here mentioned other language solution.

' Include namespace system
Imports System 
'  Vb.net program for
'  Calculate simple interest
Public Class Interest
    ' Method which is take three parameters
    ' And calculates that simple interest
    ' Here time is form in year
    ' rate is form of annual interest rate
    Public Shared Sub simpleInterest(ByVal principle As Double, 
                                     ByVal time As Double, 
                                     ByVal rate As Double)
        ' Display parameters values
        Console.WriteLine("Principal : {0}", principle)
        Console.WriteLine("Time : {0}", time)
        Console.WriteLine("Rate : {0}", rate)
        ' Calculate interest
        Dim amount As Double = (principle * time * rate) / 100
        ' Display amount
        Console.WriteLine("Simple Interest : {0} "&vbLf, amount)
    End Sub
    Public Shared Sub Main(ByVal args As String())
        ' Test Cases
        simpleInterest(1500, 3, 7.3)
        simpleInterest(170.4, 7, 3.4)
    End Sub
End Class

Output

Principal : 1500
Time : 3
Rate : 7.3
Simple Interest : 328.5

Principal : 170.4
