During August 2025, 24wh1a05z8 developed a user-facing electricity billing calculator for the NareshCSE/Java24CSEF repository. The feature prompts users for previous and current meter readings, calculates units consumed, and applies tiered pricing logic to determine the final bill. Built in Java, the solution demonstrates foundational skills in basic input/output and conditional logic, resulting in a modular and testable codebase. The implementation focuses on clear user interaction and scalable pricing computation, providing a practical billing workflow ready for quality assurance. While the work addressed a single feature, it reflects a solid grasp of core Java concepts and structured problem-solving.
