Last Updated : 06 Mar, 2019

The getCreationTime() function is a part of java.util.zip package. The function returns the Creation Time of a specific ZipEntry or null if the creation time is not specified. The function returns FileTime Object, which represents the creation time of the ZipEntry . Function Signature :

public FileTime getCreationTime()

Syntax :

zip_entry.getCreationTime();

Parameters :No parameter is required for this function. Return value :The function returns FileTime Object, which represents the creation time of the ZipEntry . Exceptions :The function does not throw any exception. Below programs illustrates the use of getCreationTime() function Example 1: We will create a file named zip_file and get the zip file entry using getEntry() function and then get the CreationTime of the specified ZipEntry."file.zip" is a zip file present in f: directory. we will take a ".zip" file as ZipEntry

Java

// Java program to demonstrate the
// use of getCreationTime() function

import java.util.zip.*;
import java.util.Enumeration;
import java.util.*;
import java.io.*;
import java.nio.file.attribute.*;

public class solution {
    public static void main(String args[])
    {
        try {
            // Create a Zip File
            ZipFile zip_file = new ZipFile("f:\\file1.zip");

            // get the Zip Entry using
            // the getEntry() function
            ZipEntry entry = zip_file.getEntry("file.zip");

            // Get the CreationTime
            // using the getCreationTime()
            // function
            FileTime input = entry.getCreationTime();

            // Display the CreationTime
            System.out.println("CreationTime : " + input.toString());
        }
        catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}

Output:

CreationTime : 2019-02-21T21:09:35.688822Z

Example 2: We will create a file named zip_file and get the zip file entry using getEntry() function and then get the CreationTime of the specified ZipEntry."file.zip" is a zip file present in f: directory. we will take a ".cpp" file as ZipEntry

Java

// Java program to demonstrate the
// use of getCreationTime() function

import java.util.zip.*;
import java.util.Enumeration;
import java.util.*;
import java.io.*;
import java.nio.file.attribute.*;

public class solution {
    public static void main(String args[])
    {
        try {
            // Create a Zip File
            ZipFile zip_file = new ZipFile("f:\\file1.zip");

            // get the Zip Entry using
            // the getEntry() function
            ZipEntry entry = zip_file.getEntry("file1.cpp");

            // Get the CreationTime
            // using the getCreationTime()
            // function
            FileTime input = entry.getCreationTime();

            // Display the CreationTime
            System.out.println("CreationTime : " + input.toString());
        }
        catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}

Output:

CreationTime : 2018-12-07T13:11:25.357749Z
