Dependency Injection is one of the foundational techniques in Java backend development, helping build resilient and scalable applications tailored to modern software demands. DI is used to simplify dependency management by externalizing dependencies from the class itself, streamlining code maintenance, fostering modularity, and enhancing testability.
Why is this technique crucial for Java developers? How does it effectively address common pain points? In this article, I present to you the practical benefits, essential practices, and real-world applications of Dependency Injection. Let’s explore the practical strategies that underlie Dependency Injection in Java backend applications.
