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);
The above seems sloppy. But what is better?
private String contentDirectoryStr = "/tmp/";
private File contentDirectory = new File(contentDirectoryStr);
Looks just as bad.
What is a common convention you follow to describe same things of different type?
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.
回答1:
My first thought would be to use the same name, but differentiate based on the type.
Example:
private String contentDirStr = "/tmp/";
private File contentDirFile = new File(contentDirStr);
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.
