encapsulation examples

Hi, I have searched and searched for a code example which shows some basic programming that does not use encapsulation and then the same code but changed to represent encapsulation...

All i can find is examples of encapsulated code

Could someone please post me some simple code snippets

-snippet of some simple code that doesnt use encapsulation

and

-snippet of that same code modified to represent encapsulation

any help would be greatley appriciated

Is this for a class?

' A class without encapsulation:

Code:

---

Class A
  Public Field As Integer

  Public Function MethodA() As Integer
        Return Field + 1
  End Function
End Class

---

The class above exposes its field directly to the user so it can be accessed from anywhere.

Code:

---

Class B
  Private _Field As Integer
  Private Function MethodB() As Integer
      Return _Field + 1
  End Function

  Public Property Field As Integer
      Get
          Return _Field
      End Get
      Set(ByVal value As Integer)
          _Field = value
      End Set
    End Property

    Public ReadOnly Property Result As Integer
      Get
          Return MethodB
      End Get
    End Property
End Class

---

The second method encapsulates a private field which can be accesses only through a public property and you can perform validation in the 'Set' block. Also it encapsulates a 'business logic' method (MethodB) and only returns result through the readonly property. Using this technique you can protect your private members from any outside interference.
