Convert Milliseconds to Date in Java

Calendar and Date class instance methods are used to convert millis to Date.

This example shows how to convert Milliseconds to Date in Java.

Converting Milliseconds to Date in Java – Millis to Date Example

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class MillisToDate {

    public static void main(String args[]) {

        //Converting milliseconds to Date using java.util.Date
        //current time in milliseconds
        long currentDateTime = System.currentTimeMillis();

        //creating Date from millisecond
        Date currentDate = new Date(currentDateTime);

        //printing value of Date
        System.out.println("current Date: " + currentDate);

        DateFormat df = new SimpleDateFormat("dd:MM:yy:HH:mm:ss");

        //formatted value of current Date
        System.out.println("Milliseconds to Date: " + df.format(currentDate));

        //Converting milliseconds to Date using Calendar
        Calendar cal = Calendar.getInstance();
        cal.setTimeInMillis(currentDateTime);
        System.out.println("Milliseconds to Date using Calendar:" + df.format(cal.getTime()));

        //copying one Date's value into another Date in Java
        Date now = new Date();
        Date copiedDate = new Date(now.getTime());

        System.out.println("original Date: " + df.format(now));
        System.out.println("copied Date: " + df.format(copiedDate));
    }

}

import java.text.DateFormat;

import java.text.SimpleDateFormat;

import java.util.Calendar;

import java.util.Date;

public class MillisToDate {

public static void main(String args[]) {

//Converting milliseconds to Date using java.util.Date

//current time in milliseconds

long currentDateTime = System.currentTimeMillis();

//creating Date from millisecond

Date currentDate = new Date(currentDateTime);

//printing value of Date

System.out.println("current Date: " + currentDate);

DateFormat df = new SimpleDateFormat("dd:MM:yy:HH:mm:ss");

//formatted value of current Date

System.out.println("Milliseconds to Date: " + df.format(currentDate));

//Converting milliseconds to Date using Calendar

Calendar cal = Calendar.getInstance();

cal.setTimeInMillis(currentDateTime);

System.out.println("Milliseconds to Date using Calendar:" + df.format(cal.getTime()));

//copying one Date's value into another Date in Java

Date now = new Date();

Date copiedDate = new Date(now.getTime());

System.out.println("original Date: " + df.format(now));

System.out.println("copied Date: " + df.format(copiedDate));

}

Output:

current Date: Wed Feb 29 01:58:46 VET 2012
Milliseconds to Date: 29:02:12:01:58:46
Milliseconds to Date using Calendar:29:02:12:01:58:46
original Date: 29:02:12:01:58:46
copied Date: 29:02:12:01:58:46
