📎 About :

• 🏋️‍♂️ This lab demonstrates the concepts of dependency injection (DI) and inversion of control (IoC) in Java. It provides both a static and dynamic presentation of how dependencies can be injected into classes.

📎 Features :

• Static Presentation: Use static instantiation to create instances of DOA and Business implementations and inject dependencies using setter methods.
• Dynamic Presentation: Read configuration from a file and dynamically instantiate DAO and Business implementations based on class names specified in the config.txt file.
• Interface Abstraction: Define contracts through the IBusiness and IDao interfaces for loose coupling and easy swapping of implementations.
• Multiple Implementations: Support multiple implementations of IDao and IBusiness interfaces for retrieving data from different sources.
• File Configuration: Configure the application behavior by specifying implementations in the configuration file config.txt, allowing for easy modification without code changes.
