是否应该使用大写命名来声明Java常量变量? [英] Should I use upper-case naming to declare java constant variables?

问题描述

我的问题:常量Java变量(在方法内)的名称应大写吗?

My question: Should names of constant Java variables (within methods) be upper-case?

我一直给人以

a)如果变量永远不会更改，则应将其声明为final(以显示/强制其不会更改)b)应该以大写字母命名

a) if a variable is never going to change, it should be declared final (to show/enforce that it won't change) b) it should be named in upper-case

但是，我在日食中注意到，将变量(在方法内)更改为最终/常量，随后将其重构/重命名为以下内​​容:

However, I've noticed in eclipse, when changing a variable (within a method) to be final/constant, and subsequently refactoring/renaming it to something like below:

final int NODE_COUNT = 3;

我收到以下警告:

不建议使用此名称.根据约定，局部变量的名称应以小写字母开头.

This name is discouraged. According to convention, names of local variables should start with a lowercase letter.

这让我想知道大写规则在这种情况下是否不适用(即方法中的最终变量).

Which makes me wonder if the upper-case rule doesn't apply in this instance (i.e. final variable within a method).

推荐答案

在方法中，您没有常量，只有局部变量，可以是 final .因此，从小写字母开始使用普通的camelCase非常适合在那里.

Within methods you don't have constants, you just have local variables, that can be final. So using normal camelCase starting with lowercase is perfectly suiting there.
