Answer
Constructor Injection ensures dependencies are set at creation, supporting immutability.
Constructor Injection mandates dependencies be provided during object creation, which prevents changes to dependencies after the object is constructed, supporting immutable designs. For example, a PaymentService can be constructed with its required processors at startup.
