Java: Constructor vs Field Injection
Answer
It allows easy mocking of dependencies. Frame the concept in practical terms so you can explain it during interview discussion.
Constructor injection makes it simple to pass mock objects during testing, improving test isolation. For example, in testing a ShoppingCart, you can inject a mock InventoryService to simulate different scenarios without affecting other tests.
