我正在做一个项目，该项目的模块为文件或文件夹信息".这意味着，我需要所有打开的文件和打开的目录详细信息.

I'm doing a project that has a module as "File or folder information". It means, I need all open files and open directory details.

例如:

如果用户打开了一个文件"aa.txt"，并且该文件位于"bb目录"中；输出应该像

If one file "aa.txt" was open by user, and the file is in "bb directory"; the output should be like

推荐答案

请查看Java的

Please have a look at Java's java.io.File API. You will get most of the things there. For checking if the file has been modified, you can use lastModified() method.

JDK 7 提供了新的 WatchService API和文件更改通知API .您可以在 此处 中阅读.
