Money pattern

[iluwatar]

Description

The Money design pattern, as described by Martin Fowler, provides a way to encapsulate monetary values and their associated currencies. This pattern helps in handling calculations and operations involving money in a clear and reliable manner, avoiding common issues like rounding errors and ensuring currency consistency.

Key Elements of the Money Pattern:

• Encapsulation of a monetary value along with its currency.
• Operations involving monetary values, such as addition, subtraction, and multiplication, which consider the currency.
• Proper handling of rounding issues.
• Conversion between different currencies using an exchange rate.

References

• Martin Fowler's Money Pattern
• Patterns of Enterprise Application Architecture by Martin Fowler (Page 303)

Acceptance Criteria

1. Create a Money class that encapsulates a monetary value and its associated currency.
2. Implement operations (addition, subtraction, multiplication) on the Money class that handle currency consistency and rounding issues.
3. Add functionality for currency conversion with appropriate handling of exchange rates.

Hi,
I am very enthusiasm to lean on that issue. I read the topic of this pattern but what is the purpose of this issue.
Would I have to code this pattern in Java ? I don't see your request.
Please I would like to have more informations about your aim.

Best regards.
Sophonie.

Yes @sophonie, I'm sorry for the poor description in this issue. The aim is to create an example implementation of Money pattern in this repository. You can check how the other patterns have been implemented and follow the same style. There are also brief contribution instruction at https://github.com/iluwatar/java-design-patterns/wiki/01.-How-to-contribute

Please let me know if you want to try implementing this pattern.

I've submitted a PR for this issue. See -> #1673 Sorry if I didn't let you know before actually working on the pattern. @iluwatar
