How to convert Date represented as a String to milliseconds?

how to convert java string to Date object

In my Java code I have input String like 05.10.2011 which I need to convert to milliseconds.

So:

String someDate = "05.10.2011";

I have to convert to match milliseconds format.

Your question is a little confusing because `05.10.2011` doesn't mean anything without some timezone and time. — Amir Raminfar, Dec 12 '11 at 16:13
in this particular case, I'm receiving only string in format "dd.MM.YYYY" — user696847, Dec 12 '11 at 16:16

String someDate = "05.10.2011";
SimpleDateFormat sdf = new SimpleDateFormat("MM.dd.yyyy");
Date date = sdf.parse(someDate);
System.out.println(date.getTime());

I think you mean `MM.dd.yyyy` – Amir Raminfar Dec 12 '11 at 16:22

You can use Java's SimpleDateFormat to easily convert to a Date instance.

SimpleDateFormat formatter = new SimpleDateFormat("MM.dd.yyyy"); // Month.Day.Year

Date d = formatter.parse(inputString);
long timestamp = d.getTime();

use the simpleDateFormat which takes a string and converts it to Date then call the getTime() to get the date in milliseconds format

@JB-Nizet is correct, to adapt to your code replace **new SimpleDateFormat("mm/dd/yyyy")** with **new SimpleDateFormat("mm.dd.yyyy")** – Adel Boutros Dec 12 '11 at 16:16
You want "MM.dd.yyyy", not "mm.dd.yyyy". – Jason Nichols Dec 12 '11 at 16:26
