There are multiple ways to get created date of a file.
//Return creation time in milliseconds
private static long getCreateTime_approach1(String filePath) throws Exception {
Path path = new File(filePath).toPath();
FileTime creationTime = (FileTime) Files.getAttribute(path, "creationTime");
return creationTime.toMillis();
}
Approach 2: Using 'Files.readAttributes' method
//Return creation time in milliseconds
private static long getCreateTime_approach2(String filePath) throws Exception {
Path path = new File(filePath).toPath();
BasicFileAttributes attr = Files.readAttributes(path, BasicFileAttributes.class);
FileTime creationTime = attr.creationTime();
return creationTime.toMillis();
}
Find the below working application.
App.java
package com.sample.app;
import java.io.File;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.attribute.BasicFileAttributes;
import java.nio.file.attribute.FileTime;
import java.util.Date;
public class App {
// Return creation time in milliseconds
private static long getCreateTime_approach1(String filePath) throws Exception {
Path path = new File(filePath).toPath();
FileTime creationTime = (FileTime) Files.getAttribute(path, "creationTime");
return creationTime.toMillis();
}
private static long getCreateTime_approach2(String filePath) throws Exception {
Path path = new File(filePath).toPath();
BasicFileAttributes attr = Files.readAttributes(path, BasicFileAttributes.class);
FileTime creationTime = attr.creationTime();
return creationTime.toMillis();
}
public static void main(String[] args) throws Exception {
String filePath = "/Users/krishna/Documents/TechnicalDocuments/glob.txt";
long time1 = getCreateTime_approach1(filePath);
Date date1 = new Date();
date1.setTime(time1);
long time2 = getCreateTime_approach2(filePath);
Date date2 = new Date();
date2.setTime(time2);
System.out.println(date1);
System.out.println(date2);
}
}
