How to convert one formatted date String to another format

Question

I have a JDateChooser bean panel named basDate. When i execute System.out.println(basDate.getText()); it returns 12.02.2014 But i must convert and edit it to 2014-02-12 00:00:00.000

Just i want edit and assign new output to a variable coming as "12.02.2014" value as "2014-02-12 00:00:00.000"

I use Netbeans Gui Builder.

Since the input date is a string in a different format from what you want, you need to two SimpleDateFormats. One to parse the String to a Date and another to format the Date to a different format.

Test this out. input 12.02.2014 output 2014-12-02 00:00:00:000

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.Logger;

public class MyDateFormat {

    public static void main(String[] args){
        String inputStringDate = "12.02.2014";
        SimpleDateFormat inputFormat = new SimpleDateFormat("dd.MM.yyyy");
        Date inputDate = null;
        try {
            inputDate = inputFormat.parse(inputStringDate);
        } catch (ParseException ex) {
            Logger.getLogger(MyDateFormat.class.getName()).log(Level.SEVERE, null, ex);
        }

        SimpleDateFormat outputFormat = new SimpleDateFormat("yyyy-dd-MM HH:mm:ss:SSS");
        String outputStringDate = outputFormat.format(inputDate);

        System.out.println(outputStringDate);      
    }
}
