how to get the date from the string representation of date

[neha priya]

hello everyone,

i have a datecombobox named endDateCombo.....i have set the value of it by providing

  SimpleDateFormat dateTimeFormat = new SimpleDateFormat("MMM dd,yyyy hh:mm:ss a zzz");

              currentDate= Calendar.getInstance();
		endDateCombo = new DateComboBox(new DefaultDateModel()) ;
		endDateCombo.setFormat(dateTimeFormat);
		endDateCombo.setEditable(true);
		
		endDateCombo.setTimeDisplayed(true);
		endDateCombo.setCalendar(currentDate);
		endDateCombo.setDate(null);

  

now i am extracting the value from endDateCombo as:

  String endDate=endDateCombo.getSelectedItem.toString(); 

Once i have done this i need to know a way so that am able to extract the Date and time from the above string specified so that i can typecast it to Timestamp and perform comparisons.

please help

thanks.

I think you need to use method :

dateTimeFormat.parse("value comes here");

thanks for the reply...

you mean that i need to write the following statements to get the date and time from the string representation:

Date newDate= dateTimeFormat.parse(endDate); 

 
   

and once i get the date representation i'll write the following statement to get the timestamp:

 Timestamp endTime = new Timestamp(newDate.getTime());   

please reply
thanks

If you want java.util.Date here is example:

         
       

import java.text.ParsePosition;
import java.text.SimpleDateFormat;
import java.util.Date;

public class MainClass {

  public static void main(String[] a) {
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
    String input[] = { "2013-10-01 Vancouver, B.C.", 
                       "1248-03-01 Ottawa, ON",
                       "1323-06-06 Toronto, ON" };
    for (int i = 0; i < input.length; i++) {
      ParsePosition pp = new ParsePosition(0);
      Date d = formatter.parse(input[i], pp);
      if (d == null) {
        System.err.println("Invalid date in " + input[i]);
        continue;
      }
      String location = input[i].substring(pp.getIndex());
      System.out.println(" on " + d + " in " + location);

    }
  }
}
/*
 Output: 
 
 on Tue Oct 01 00:00:00 PDT 2013 in  Vancouver, B.C.
 on Sun Mar 01 00:00:00 PST 1248 in  Ottawa, ON
 on Mon Jun 06 00:00:00 PST 1323 in  Toronto, ON

*/ 
 

and if the java.sql.Date

 
String dateStr = "2013-10-01";
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-mm-dd");
 java.sql.Date effect_from = new java.sql.Date(formatter.parse(dateStr).getTime());

thanks for the replies...am trying the ways suggested by you all to get my problem solved....

@ swastik dey:

  Date newDate= dateTimeFormat.parse(endDate);   
    

i tried the way you suggested...

but am getting errors:

Hope it would help!

Don't put such long lines inside code tags.

@Campbell Ritchie:Sorry..will take care from next time

Apologies accepted. It's just that such long lines expand the window beyond the width of the screen and are difficult to read.
