Boxing is a process in which object instances are created
and copy values in to that instance.
Unboxing is vice versa of boxing operation where the value
is copied from the instance in to appropriate storage
location.
Below is sample code of boxing and unboxing where integer
data type is converted in to object
and then vice versa.
Dim x As Integer
83
Dim y As Object
x = 10
‘ boxing process
y = x
‘ unboxing process
x = y
