public class AgeFileFilter extends AbstractFileFilter implements Serializable
For example, to print all files and directories in the current directory older than one day:
File dir = new File(".");
// We are interested in files older than one day
long cutoff = System.currentTimeMillis() - (24 * 60 * 60 * 1000);
String[] files = dir.list( new AgeFileFilter(cutoff) );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}

If last modification time equals cutoff and newer files are required, file IS NOT selected. If last modification time equals cutoff and older files are required, file IS selected.
