Каков лучший способ проанализировать много сложных параметров командной строки в Java?

Попробуйте следующее

Option Explicit
Public Sub EMail()
    Application.ScreenUpdating = False

    Dim OutApp As Object
    Set OutApp = CreateObject("Outlook.Application")

    Dim Sht As Worksheet
    Set Sht = ThisWorkbook.Sheets("Sheet1")

    Dim Cell As Range
    For Each Cell In Sht.Range("A2", Sht.Range("A100").End(xlUp))
        DoEvents

       If Sht.Cells(Cell.Row, "B").Value Like "?*@?*.?*" And _
           Sht.Cells(Cell.Row, "C").Value = "0" Or _
           Sht.Cells(Cell.Row, "D").Value = "0" Or _
           Sht.Cells(Cell.Row, "E").Value = "0" Then               

            Dim MissingItem As String
            Select Case "0"
                Case Sht.Cells(Cell.Row, "C").Value
                    MissingItem = "KPI's"
                Case Sht.Cells(Cell.Row, "D").Value
                    MissingItem = "Comments"
                Case Sht.Cells(Cell.Row, "E").Value
                    MissingItem = "Org Chart"
            End Select

            Dim OutMailKPI As Object
            Set OutMailKPI = OutApp.CreateItem(0)

            With OutMailKPI
                .To = Sht.Cells(Cell.Row, "B").Value
                .Subject = "Reminder"
                .Body = "Dear, " & Sht.Cells(Cell.Row, "A").Value _
                      & vbNewLine & vbNewLine & MissingItem
                .Display
            End With

        End If
    Next Cell

    Set OutApp = Nothing
    Application.ScreenUpdating = True
End Sub
