  This Java example shows how to determine last modification time of a particular
  file or directory using lastModified method of Java File class.
*/
 
import java.io.*;
import java.util.Date;
 
public class GetLastModificationTimeOfAFile {
 
  public static void main(String[] args) {
 
    //create file object
    File file = new File("C://FileIO//demo.txt");
 
    /*
     * To determine last modification time of a particular file or directory, use
     * long lastModified() method of Java File class.
     *
     * This method returns long representing the time file was last modified as
     * milliseconds since Jan 01, 1970 00:00:00. This
     * method returns 0L if the file does not exists or in case of IOException.
     *
     */
 
     long lastModified = file.lastModified();
 
     System.out.println("File was last modifed at : " + new Date(lastModified));
  }
}
 
/*
Typical output would be
File was last modifed at : Sun Jan 06 18:24:01 EST 2008
