Imports System

Public Class Program
    Public Shared Sub Main(ByVal args As String())
        Dim a As Integer = 1
        Dim b As Integer = 2

        If (a = 1) AndAlso (b = 2) Then
            Console.WriteLine("a = 1 AND (&&) b = 2")
        End If

        If (a = 1) OrElse (b = 1) Then
            Console.WriteLine("a = 1 OR (||) b = 1")
        End If

        If a <> b AndAlso b = 2 Then
            Console.WriteLine("a != b AND (&&) b == 2")
        End If

        If a > b OrElse b = 2 Then
            Console.WriteLine("a > b OR (||) b == 2")
        End If

        If Not (a > b) Then
            Console.WriteLine("!(a > b)")
        End If
    End Sub
End Class




' run:
'
' a = 1 AND (&&) b = 2
' a = 1 OR (||) b = 1
' a != b AND (&&) b == 2
' a > b OR (||) b == 2
' !(a > b)
