Nullable Types
Nullable types
allow a variable to have a
null value
, providing a way to represent the
absence of a value
in
type-safe languages
. This is particularly useful in
database operations
and
optional data scenarios
, reducing the risk of
null reference errors
by explicitly handling nullability.
