java-calculator

Working repository Heavily object-oriented calculator in Java to train OOP skills and master Java.

Roadmap

1. Implement basic math operations as classes and write unit tests for them. Get familiar with Gradle and Idea.
2. Implement RPN to parse string input to convert "2 + (3 / 4)" into Operation objects.
3. Implement expressions and solvers for solving systems like "2 + x = 10".
4. Wrap existing code into REST-API service.
5. Implement optical character recognition (OCR) feature. With OCR we are going to convert image with numeric expression into text, and from there - to domain model objects.
6. Implement automatic expression detection using line and objects detection.
