推荐答案

我想要基于创建日期的文件列表.

I want list of file based on my creation date.

如前两个答案所指出的，您可以根据修改日期对文件进行排序:

As the two previous answers pointed out, you can sort the files according to the modification date:

file.lastModified()

但是修改日期已更新，例如在重命名文件的瞬间.因此，这将无法代表创建日期.

But the modification date is updated e.g. in the instant of renaming a file. So, this won't work to represent the creation date.

不幸的是，创建日期不可用，因此您需要重新考虑基本策略:

Unfortunately, the creation date is not available, thus you need to rethink your basic strategy:
