Is the object-oriented programming principle fundamental to using the Spring Framework?

Yes, the principle of object-oriented programming (OOP) is fundamental for using the Spring Framework. Spring is built on Java, which is an object-oriented language itself, and uses OOP concepts such as encapsulation, inheritance, and polymorphism.

Spring actively applies the principles of Inversion of Control (IoC) and Dependency Injection (DI), which are implemented through objects and their interactions. For example, Spring components are objects that the container creates and manages their lifecycle.

Therefore, understanding OOP is necessary for effective work with Spring, as the architecture and patterns of the framework are built on these principles.
