Answer
Constructor injection ensures dependencies are set and promotes immutability.
Constructor injection in Spring enforces that all required dependencies are provided at object creation time. This makes the object's state immutable and guarantees that the object is always in a valid state. For example, if you have a ProductService that requires a ProductRepository, constructor injection ensures the repository is always available when the service is used.
