在Java中定义常量字符串? [英] Defining constant string in Java?

问题描述

我有一个常量字符串列表，需要在Java程序中的不同时间显示.

I have a list of constant strings that I need to display at different times during my Java program.

在C语言中，我可以在代码顶部定义这样的字符串:

In C I could define the strings like this at the top of my code:

#define WELCOME_MESSAGE "Hello, welcome to the server"
#define WAIT_MESSAGE "Please wait 5 seconds"
#define EXIT_MESSAGE "Bye!"

我想知道在Java中做这种事情的标准方法是什么?

I am wondering what is the standard way of doing this kind of thing in Java?

推荐答案

通常，您需要在类顶部定义它:

Typically you'd define this toward the top of a class:

public static final String WELCOME_MESSAGE = "Hello, welcome to the server";

当然，请根据使用此常量的位置使用适当的成员可见性( public / private / protected ).

Of course, use the appropriate member visibility (public/private/protected) based on where you use this constant.
