FileSet Package / Class for Java

Question

Can anyone suggest a FileSet package / class in Java. By FileSet, I mean a set of files and directories along with inclusion and exclusion rules with a regular expression (similar to Apache Ant). Thank.

Answer 1

You can use File#listFiles()where you pass FileFilteror FilenameFilterwhere you can specify the desired template in the method accept().

eg.

File[] txtFiles = file.listFiles(new FilenameFilter() {
    @Override public boolean accept(File dir, String name) {
        return name.endsWith(".txt"); // You can use String#matches() as well.
    }
});

Answer 2

Apache Commons IO FileUtils may be what you want. It has the ability to identify files with an additional filter for file names that you can implement yourself.

listFiles() iterateFiles() .
