Java Swing Calculator

A functional desktop calculator built with Java featuring a Graphical User Interface (GUI). This project was developed as part of my coursework in the Information and Computer Systems program at Camosun College (Fall 2025).

Features

• Interactive GUI: Built using the Java Swing framework for a responsive user experience.
• Advanced Operations: Supports standard arithmetic (addition, subtraction, multiplication, division) plus advanced functions like square root ($\sqrt{x}$), square ($x^2$), reciprocal ($1/x$), and percentage (%).
• Robust Logic: Implements separate logic for single-operand and dual-operand operations.
• Error Handling: Features custom exception handling for mathematical errors, such as division by zero.

Technical Highlights

• Frameworks: Java Swing & AWT (JFrame, JPanel, JTextField, GridLayout).
• Clean Code Architecture: * Separation of Concerns: Distinct separation between the UI logic (Calculator.java) and the mathematical engine (Operation.java).
• Event-Driven Programming: Implements ActionListener for efficient user input management.
