Imposing two conditions on FileUtils listFiles in java

I want to pick only those files which have "txt" extension and are more than 1 minute old. Is there a way to enforce both of these conditions in the listFiles method?

To ensure it picks only txt files, this is how I did

    Collection<File> myFiles = FileUtils.listFiles(FileUtils.getFile(inputPath),
                                   FileFilterUtils.suffixFileFilter(".txt"),
                                   null);

I could find isFileOlder() method in FileUtils but how to impose both restrictions to it?

Please suggest some way.

Solution

  • You want to use the AndFileFilter.

    This lets you combine any two file filters as a Boolean. As there isn't a delivered file filter for the age criteria, you'll still need to create one, following the lines of the other comment.
