We Should Write Java Code Differently: The DI Confusion

Inversion of Control is one of the most impactful ideas in software engineering. It fundamentally changed how we structure applications — making code testable, modular, and composable. Dependency Injection, its most common implementation, became the backbone of virtually every modern Java framework. But somewhere along the way, DI acquired a second job. And that second job is quietly causing problems. Assembly vs. Provisioning DI was designed to solve one problem: assembling an appl
