I'm looking for a way to get a list of files that match a pattern (pref regex) in a given directory.
I've found a tutorial online that uses apache's commons-io package with the following code:
Collection getAllFilesThatMatchFilenameExtension(String directoryName, String extension)
{
File directory = new File(directoryName);
return FileUtils.listFiles(directory, new WildcardFileFilter(extension), null);
}
But that just returns a base collection (According to the docs it's a collection of java.io.File
). Is there a way to do this that returns a type safe generic collection?
See File#listFiles(FilenameFilter).
File dir = new File(".");
File [] files = dir.listFiles(new FilenameFilter() {
@Override
public boolean accept(File dir, String name) {
return name.endsWith(".xml");
}
});
for (File xmlfile : files) {
System.out.println(xmlfile);
}
