Spring Framework Master Class - Java Spring the Modern Way - Quick Introduction to the Spring Framework

The video provides an overview of the Spring Framework, focusing on its role as a dependency injection framework. It explains the concept of dependencies in web applications, highlighting the importance of loose coupling over tight coupling. The video introduces key Spring annotations like @Component and @Autowired, which help manage dependencies. It concludes with a discussion on important terminologies related to the Spring Framework, such as beans, auto wiring, and inversion of control.

What is the primary function of the Spring Framework?

• A web development framework

• A dependency injection framework

• A database management system

• A user interface library

In a typical web application, which layer is responsible for handling the user interface?

• Data layer

• Business layer

• Web layer

• Service layer

What is the problem with directly instantiating dependencies in code?

• It results in tight coupling

• It leads to loose coupling

• It simplifies the code

• It makes the code more efficient

How does Spring Framework help in achieving loose coupling?

• By directly instantiating dependencies

• By hardcoding dependencies

• By removing the need for dependencies

• By using annotations to manage dependencies

Which annotation is used to indicate that a class should be managed by Spring?

• @Service

• @Autowired

• @Repository

• @Component

What does the @Autowired annotation do in Spring?

• It defines a new bean

• It injects dependencies into a class

• It manages the lifecycle of a bean

• It creates a new instance of a class

What are beans in the context of Spring Framework?

• Objects managed by the Spring Framework

• Java classes that are not managed by Spring

• Database entities

• User interface components

What is the process of identifying and populating dependencies in Spring called?

• Auto wiring

• Inversion of control

• Bean management

• Dependency injection

What does IOC stand for in the context of Spring Framework?

• Input Output Control

• Inversion of Control

• Instance of Class

• Internal Object Creation

Which component of Spring Framework is responsible for managing beans?

• User Interface

• Database Manager

• Service Layer

• Application Context
