Java：枚举或用数字编码？ [英] Java: Enum or encoding with numbers?

问题描述

我开始学习Java，我想尝试通过编写一个简单的程序来测试一些Java功能，该程序将构建一系列卡片并打印出所有卡片的列表。当我开始这样做时，我不确定使用数字代表卡片套装和排名或使用枚举是否更有效。我想知道哪个在效率，可读性和惯例方面更好？迭代哪个更好？谢谢。

I am starting to learn Java and I'd like to try to test out a few Java features by writing a simple program that will build an array of a deck of cards and will print out a list of all the cards. When I started doing this I was unsure whether it is more efficient to use numbers to represent the cards suits and ranks or to use enums. I'd like to know which is better in terms of efficiency, readability and convention? Which is better for iteration? Thanks.

推荐答案

可读性：枚举

约定：枚举

效率：在您知道自己遇到问题之前，您不应该关心。由于使用Enums，您不太可能遇到性能问题。

Efficiency: You shouldn't care until you know you have a problem. It is very unlikely that you will ever encounter a performance problem due to the use of Enums.
