Format date with SimpleDateFormat Java

Question

I have a date string as

"Wed Jul 01 08:16:13 PDT 2015"

I am trying to parse it with this SimpleDateFormat

SimpleDateFormat valueDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

this way:

Date parsedDate1 = valueDateFormat.parse("Wed Jul 01 08:16:13 PDT 2015");

It is giving me parse error as:

java.text.ParseException: Unparseable date: "Wed Jul 01 08:16:13 PDT 2015" (at offset 0)

How can I get a date in above simple date format from the string

your Date formate and simpledateformat formate are different.. that is why you are getting parseException.... — kavetiraviteja, Jul 01 '15 at 18:34
@ravitejaKaveti but then how can I convert string to that format — Akshay, Jul 01 '15 at 18:35
The `SimpleDateFormat` construct takes a `String` for the template. Your template does not match the data you are trying to parse. You can learn more about how to form the correct template here: http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html — Dan Harms, Jul 01 '15 at 18:45

Try this:

DateFormat originalFormat = new SimpleDateFormat("EEE MMM dd hh:mm:ss zzz yyyy");
DateFormat targetFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = originalFormat.parse("Wed Jul 01 08:16:13 PDT 2015");
String formattedDate = targetFormat.format(date); 
System.out.println(formattedDate);

I suspect you don't realy understand the consept of the SimpleDateFormat.

After you define the template with :

        SimpleDateFormat valueDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

The valueDateFormat could parse Date object acording to it, it not take just a String you have and convert it. it take Date object.

Your date string ("Wed Jul 01 08:16:13 PDT 2015") doesn't match your pattern ("yyyy-MM-dd hh:mm:ss")

Write correct pattern which matches date string (first goes Day of week, than month in year, etc.)

I want to convert string to that format – Akshay Jul 01 '15 at 18:33
For that, first you need to convert String to Date with correct format, and then convert Date to new String format – Max77 Jul 01 '15 at 18:36

For the formats like this I created a helper method:

public Date parseString(String date) {

    String value = date.replaceFirst("\\D+([^\\)]+).+", "$1");

    //Timezone could be either positive or negative
    String[] timeComponents = value.split("[\\-\\+]");

    long time = Long.parseLong(timeComponents[0]);
    int timeZoneOffset = Integer.valueOf(timeComponents[1]) * 36000; // (("0100" / 100) * 3600 * 1000)

    //If Timezone is negative
    if(value.indexOf("-") > 0){
        timeZoneOffset *= -1;
    }

    //Remember that time could be either positive or negative (ie: date before 1/1/1970)
    //time += timeZoneOffset;

    return new Date(time);
}

It returns date object from Date string so you can format your string like this:

Date date = parseString("Wed Jul 01 08:16:13 PDT 2015");

And after that you can easily format given date variable.

try this..

public static void main(String[] a) 
{

  SimpleDateFormat valueDateFormat = new SimpleDateFormat("EEE MMM yy hh:mm:ss");
  try {
    Date parsedDate1 = valueDateFormat.parse("Wed Jul 01 08:16:13 PDT 2015");
    System.out.println(parsedDate1);
  } catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
  }
 }
