A simple calculator developed in Java, the first of many personal Java projects.
This project was built as a learning exercise to understand Java GUI, event handling, and testing with JUnit.
- Basic Math Operations: Addition, subtraction, multiplication, division
- Square Root Calculation
- Chain Operations: Use the result of the last calculation as the first input for the next
- Error Handling: Gracefully handles division by zero with GUI-friendly feedback
- Java 21+ – Download Java
Thanks to Tap Tap for the inspiration to build this project.
