public static final
或
private static final
考虑仅从类本身使用常量的情况。哪种风格更合适？

如果您只需要在课程中使用这些值，则它们应为private。通常会使事情尽可能无法访问，并且只在必要时才增加可访问性。

private。如果需要访问其值，可以使用getter。
public只有在你只有一个班级时才能真正使用。

为什么不懒惰，只做
{{1}}
我认为开始使用＆＃39; package＆＃39;访问;你可能至少需要在单元测试中使用它。然后，如果必须，您可以将其更改为公共/私人或受保护。
＆＃39;私人＆＃39;通常没有必要 - 你很少需要担心同一个包下的其他类可能搞砸了这个类。

。它们实际上是为了enum的目的而设计的，并且可以根据需要灵活地添加功能。
只需查看指向compare constants with enums，here的以下链接以及您将获得的更多链接。我刚发布了一些。

如果只需要在使用
的类中访问常量private static void
甚至只是
static final
会起作用，因为不需要在其他地方调用它。
但是，如果使用private static final作为常量，最好使用getter来调用常量，如下所示：
private static final String CONSTANTVARIABLE = "Some constant";
public String getConstantVariable() {
return CONSTANTVARIABLE;
}
