Answer
Wrapper classes allow null values, offering more flexibility.
Wrapper classes like Integer or Double can represent null values, which primitives cannot. This is useful in domain models where a value might be optional or unknown. For example, an 'Integer' field in an 'Order' object can be null if the quantity isn't set, unlike an 'int'.
