命名变量描述相同的事物但类型不同 [英] Naming variables describing the same thing but of different type

问题描述

当处理类型不同但描述相同内容的变量时，变量命名中普遍接受的方法是什么?

What is a commonly accepted approach in variable naming when dealing with variables that are of different type but describe the same thing?

private String  contentFolder    = "/tmp/";
private File    contentDirectory = new File(contentFolder);

以上内容似乎草率.但是有什么更好的呢?

The above seems sloppy. But what is better?

private String  contentDirectoryStr = "/tmp/";
private File    contentDirectory    = new File(contentDirectoryStr);

看上去也很糟糕.

用于描述不同类型的相同事物的通用约定是什么?

出于这个问题的目的，您当然可以从File获取String，并假设您在类中合法地同时需要String和File.

Thought you can of course get String from File, for the purposes of this question, assume you legitimately need both a String and a File in your class.

推荐答案

我的第一个想法是使用相同的名称，但根据类型进行区分.

My first thought would be to use the same name, but differentiate based on the type.

示例:

private String  contentDirStr  = "/tmp/";
private File    contentDirFile = new File(contentDirStr);

当然最好不要有两个对象代表同一件事，但是如果您确实需要，那就是我要为其命名的方式.

Of course it would better to not have two objects representing the same thing, but if you really need to, that's how I would go about naming them.
