30. Introduction to Frameworks (e.g., Spring Basics)

Try these first

1. 1.

   What is a framework?

   Hint

   Think about the purpose of a framework.

2. 2.

   What does Inversion of Control (IoC) mean?

   Hint

   Recall who manages the flow: the developer or the framework?

3. 3.

   What does Inversion of Control mean?

   • Developer controls flow
   • Framework controls flow
   • User controls flow

   Hint

   Think about who makes the decisions in executing the program.

4. 4.

   True or False: Dependency Injection encourages tight coupling.

   • True
   • False

   Hint

   Recall why loose coupling is advantageous.

5. 5.

   How would you implement Dependency Injection in a Java application using Spring? Illustrate with code examples.

   Hint

   Remember the concepts of annotations in Spring.

6. 6.

   Design a simple application structure using Spring Framework principles. Explain how you will enforce modularity using IoC and DI.

   Hint

   Focus on modular design and the use of interfaces.
