Boxing is an implicit conversion of a value type to the
type object
int i = 123; // A value type
Object box = i // Boxing
CASTING: casting is the process of converting a variable
from one type to another (from a string to an integer)
Unboxing is an explicit conversion from the type object to
a value type
int i = 123; // A value type
object box = i; // Boxing
int j = (int) box; // Unboxing
