A Java-based console application that converts amounts between different currencies using predefined exchange rates. This program supports conversions among six major currencies, simplifying the conversion process by using INR as an intermediary.

Features

• Convert between any two of the supported currencies: USD, EUR, GBP, CAD, AUD, and INR.
• Predefined exchange rates: The rates are hardcoded for simplicity.
• Console-based interaction: Easy-to-use console prompts guide the user through the currency conversion process.

Supported Currencies

• USD - United States Dollar
• EUR - Euro
• GBP - British Pound
• CAD - Canadian Dollar
• AUD - Australian Dollar
• INR - Indian Rupee

Exchange Rates

The exchange rates are based on the following conversions to INR (Indian Rupee):

• USD to INR: 84.10
• EUR to INR: 90.82
• GBP to INR: 109.02
• CAD to INR: 60.52

Getting Started

Prerequisites

• Java Development Kit (JDK) installed on your system
• A Java-compatible IDE or a text editor with console support
