File Last Modified Date Java

File Last Modified Date Java

In below example you will see how to get last modified date of files and print last 10 list of files in directory with their name and its last modified date descending order:

Java sample class:

package com.javahonk;

import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Comparator;
import java.util.Date;

public class FileLastModifiedDate {

	public static void main(String[] args) {
		
		//Get last modified date
		File file = new File("C:\\JavaHonk\\File\\JavaHonk.txt");
	    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
	    System.out.println("File Modified Date :- " + simpleDateFormat.format(file.lastModified()));
	    
	    
	    //Print list of file in directory and its modified date
	    File dir = new File("C:\\JavaHonk\\File");
        File[] files = dir.listFiles();
        Arrays.sort(files, new Comparator<File>()
        {
            public int compare(File f1, File f2)
            {
                return Long.valueOf(f2.lastModified()).compareTo(f1.lastModified());
            }
        });
        
        System.out.println();
        for(int i=0, length=Math.min(files.length, 10); i<length; i++) {
            System.out.println(files[i]);
        }

        System.out.println();
		for (File f : files) {
			System.out.println(f.getName() + " " + simpleDateFormat.format(new Date(f.lastModified())));		

		}						
	}
}
