原文 2014-11-27 10:36:27 2 1 java/ intellij-idea

I have not troubles with renaming packages in idea, but... I have "example" package and I want to rename it to "enum", but Idea does not allow me to do that. 我没有在想法中重命名软件包的麻烦，但是...我有“ example”软件包，我想将其重命名为“ enum”，但是Idea不允许我这样做。 When I create a new package "enum", it warns me, that I will not be able to create any java classes within. 当我创建一个新的包“ enum”时，它警告我，我将无法在其中创建任何Java类。 What is the problem??? 问题是什么？？？

You cannot rename the package to enum , because it is a reserved keyword in Java. 您不能将包重命名为enum ，因为它是Java中的保留关键字。

At the Oracle tutorial page " Naming a package " it says 在Oracle教程页面“ 命名软件包 ”中，它说

In some cases, the internet domain name may not be a valid package name. 在某些情况下，互联网域名可能不是有效的软件包名称。 This can occur if the domain name contains a hyphen or other special character, if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name, or if the package name contains a reserved Java keyword, such as "int" . 如果域名包含连字符或其他特殊字符，或者程序包名称以数字或其他字符开头的Java名称开头都是非法的， 或者程序包名称包含保留的Java关键字，则可能会发生这种情况如“ int” 。
