How to get last modified date of given file in Java?

Problem Description :

Write a program in Java that prints last modified date of given file.

Concept :

It is more simple than getting file creation date of given file. We just need to use following method of File class that is present in* package.

public long lastModified() - It returns time in milliseconds, we need to convert this time into Date.

Recommended :

Java Program :

package com.javamultiplex.FileHandling;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Scanner;

public class FileLastModifiedDate {

 public static void main(String[] args) throws IOException {

  Scanner input = null;
  try {
   input = new Scanner(;
   System.out.println("Enter file name with extension : ");
   String fileName = input.nextLine();
   if (isValidFileName(fileName)) {
    //file is present in current working directory.
    File file = new File(fileName);
    if (file.exists()) {

     long time = file.lastModified();
     String dateTime = getStringFromFileTime(time);
     System.out.println("Last modified date and time is : " + dateTime);

    } else {
     System.out.println("File doesn't exist in current directory.");
   } else {
    System.out.println("File name is not valid.");
  } finally {
   if (input != null) {

 private static String getStringFromFileTime(long time) {

  Date date = new Date();
  // setting milliseconds.
  SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");
  // Convert Date to String.
  String dateTime = dateFormat.format(date);
  return dateTime;


 private static boolean isValidFileName(String fileName) {

  //Regular expression for validating file name.
  String pattern = "^.+\\..+$";
  boolean result = false;
  if (fileName.matches(pattern)) {
   result = true;
  return result;


Output :

Output of Java program that prints last modification date of given file.
Output - How to get last modification date of given file in Java?
