Kotlin – Get File Modification Date

Kotlin – Get File Modification Date

To get the modification date of a file in Kotlin, you can use the File class from the java.io package and the Files class from the java.nio.file package. This allows you to determine when the file was last modified.

In this tutorial, we will go through the process of obtaining the last modification date of a file using Kotlin.

Steps to Get the File Modification Date in Kotlin

To retrieve the modification date of a file in Kotlin, follow these steps:

1. Import the File class from the java.io package and the Files class from the java.nio.file package.
2. Create a File object with the file path.
3. Convert the File object to a Path object using the toPath() method.
4. Use the Files.getLastModifiedTime() method to get the last modification time of the file.

Kotlin Example Program to Get File Modification Date

In the following example program, we demonstrate how to get the last modification date of a file named 'example.txt'.

Main.kt

import java.io.File
import java.nio.file.Files

fun main() {
    val filePath = "example.txt" // Replace with your file path
    val file = File(filePath)

    val lastModifiedTime = Files.getLastModifiedTime(file.toPath())
    println("Last modification date and time: $lastModifiedTime")
}

Output

Last modification date and time: 2023-10-24T13:49:04.492095047Z

The output will display the last modification date and time of the specified file.

Summary

In this Kotlin tutorial, we learned how to obtain the last modification date of a file.
