## Overview

This is a small Java console calculator. The main loop presents a menu, reads the user’s choice and operands, dispatches valid operations to arithmetic methods, and prints results before repeating or exiting. Division rejects a zero divisor. The menu, input handling, control flow, and arithmetic are all implemented in the single source file; the README documents the same workflow.

Main entry points: [`calculate/calculator.java`](https://github.com/ashutoshkumar2103/calculator/blob/main/calculate/calculator.java) (Calculator loop)
