最终静态和静态最终之间的差异 [英] Difference between final static and static final

问题描述

我找到了一个代码，它声明代码如

I found a code where it declared code like

private final static String API_RTN_SUCCESS = "0";
private final static String API_RTN_ERROR = "1";

public static final String SHARED_PREFERENCE_CONFIG = "shared_preference_config";
public static final String STARTUP_SETTING_KEY = "startup_setting";

它们之间有什么区别或相同？或者私人或公开？

What is the difference between them or are they same? Or does it differ for private or public?

推荐答案

完全没有区别。根据
8.3 .1 - 类 - Java语言规范的字段修饰符，

如果出现两个或多个（不同的）字段修饰符一个字段声明，按照惯例，虽然不是必需的，但它们的出现顺序与FieldModifier制作中的上述顺序一致。

If two or more (distinct) field modifiers appear in a field declaration, it is customary, though not required, that they appear in the order consistent with that shown above in the production for FieldModifier.

对于字段，所述生产按此顺序列出修饰符：

For fields, the said production lists the modifiers in this order:

@Annotation public protected private static final transient volatile

对于方法：

@Annotation public protected private abstract static final synchronized native strictfp

@Annotation public protected private abstract static final synchronized native strictfp
