Java Interface and Implementation Class Naming Conventions: Evolving from Redundant Prefixes to Semantic Naming
This article delves into Java interface and implementation class naming conventions, critically analyzing the redundancy of traditional prefix-based naming (e.g., ITruck, TruckImpl) and advocating for semantic naming strategies.
