Mastering Spring Framework Fundamentals - The Benefits of Dependency Injection in an Inversion of Control (IoC) Containe

What is the main advantage of allowing a container to create objects in dependency injection?

• It reduces the number of objects in the system.

• It simplifies the management of object interdependencies.

• It increases the complexity of the system.

• It allows for manual management of object interdependencies.

How does dependency injection contribute to loose coupling?

• By making objects dependent on each other.

• By allowing objects to accept dependencies rather than create them.

• By increasing the number of dependencies.

• By making objects tightly coupled.

What flexibility does dependency injection provide when swapping components like repositories?

• It allows swapping without altering the class.

• It requires changes to the class itself.

• It requires recompiling the entire system.

• It makes swapping components impossible.

What principle is closely associated with dependency injection?

• Abstraction

• Polymorphism

• Inversion of Control

• Encapsulation

Which of the following is a key benefit of dependency injection?

• Better testability

• Tighter coupling

• Reduced runtime configurability

• Increased code complexity
