The java.util.regex is bundled with the standard Java runtime. java.util.regex与标准Java运行时捆绑在一起。 (Which means that you don't need to include a separate .jar file to access it.) （这意味着您不需要包括单独的.jar文件即可访问它。）
To answer your question: It's in the rt.jar file. 要回答您的问题：它在rt.jar文件中。

The java.util.regex package was added to Java SE 1.4. java.util.regex软件包已添加到Java SE 1.4。 If you are running an older version of java than that you should really consider upgrading. 如果您正在运行Java的旧版本，则应该考虑升级。

The regex classes are in the standard rt.jar that comes with every JDK or JRE download. regex类位于每个JDK或JRE下载随附的标准rt.jar中。 You almost certainly already have them. 您几乎可以肯定已经有了它们。
