What is the role of the dependency injection container in the Spring Framework?

The Dependency Injection Container in the Spring Framework is responsible for creating, configuring, and managing the lifecycle of application objects (beans). Its role is to automatically provide the necessary dependencies to objects, simplifying the code and increasing its modularity and testability.

Main functions of the container:

• Creating class instances and managing their lifecycle.
• Injecting dependencies (via constructors, setters, or fields).
• Managing bean configuration (e.g., using annotations or XML).
• Ensuring singleton or prototype behavior of beans.

Example: if class A depends on class B, the container will automatically create an object of B and pass it to A, relieving the developer from manual creation and linking of objects.
