Java: Bean Scope
Answer
Ensures immutability and mandatory dependencies.
Constructor injection is often preferred because it allows for immutable beans, ensuring that the dependencies are provided when the bean is created and cannot be changed later. This makes the bean easier to manage and test. For instance, in a payment processing service, using constructor injection guarantees that essential dependencies like a payment gateway client are always initialized correctly.
