Cannot Format Given Object As A Date

Jun 4, 2014

When trying to convert the time zone of a date I encountered the log below. java.lang.IllegalArgumentException: Cannot format given Object as a Date..Here is what my code looks like:

1. First I will get the date from the email header by the following code.

String messageDate = (String) mail.headers["Date"];

Output: Wed, 4 Jun 2014 18:30:05 +0800

2. Next I will convert the timezone to EST.

SimpleDateFormat timeZoneConvert = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z");

timeZoneConvert.setTimeZone(TimeZone.getTimeZone(" EST"));

String l_MailDateEST = timeZoneConvert.format(messageDate.trim());

Once the code run I encounter the said error.

String Format - Conversion To Date Object

Mar 21, 2014

I have a date in the following String format "2013-03-28,19:37:52.00+00:00"  and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000"  (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e  new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz")   for conversion to Date Object
 
We are suddenly getting this exception now can't figured out what has changed ?
 
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000"
at java.text.DateFormat.parse(DateFormat.java:357)

Transform Simple Date Format - Get Calendar Date

Apr 4, 2015

Given a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?

Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...

I am looking for 01,02,03 etc...

Date Format Changes On Its Own

Jun 9, 2014

<script type="text/javascript">
function CompareDates(id)
{
var monName = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec");
var d = new Date(id);
var curr_date = d.getDate();

[code]....

why the default date format that the textbox accepts is in 'mm/dd/yyyy'.For example if i entered "13-05-2014" then it would return an error stating date is invalid.If i entered "12-05-2014" then it would return "5 Dec, 2014".I did not declare any dateformat anywhere except for the datepickers which as shown above, is 'd MMM, yyyy'.Before this happened i trialed and error many different kind of codes to try to validate the date however it all didnt work and so i reverted it all back to the original codes.Last time the dateformat that the textbox accepted was 'dd/mm/yyyy' and it worked fine with my javascript function except the validation part.

Now it still works except that the dateformat changed to 'mm/dd/yyyy'.I did try to use console.log to find out what's wrong but there were no error messages.Why has the dateformat changed by itself?

Changing Format Of Parsed Date

Aug 13, 2014

I've created a method named parseStringToDate this method takes a string parameter and parse it to the date: here is my code:

public Date parseStringToDate(String date) throws ParseException{
DateFormat formatter = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.SHORT, Locale.getDefault());
return formatter.parse(date);
}

i'm trying to parse a String to date then:

public static void main(String args[]) {
MyDate a = new MyDate();
try {
Date d = a.parseStringToDate("Wednesday, August 13, 2014 3:33 PM");
System.out.println(d);
} catch (ParseException e) {
e.printStackTrace();
}
}

As i've defined DateFormat in the method, now i'm passing it a date accordingly: "Wednesday, August 13, 2014 3:33 PM" And the output is: Wed Aug 13 15:33:00 PKT 2014

Which is not equal to the format i gave it.. how can i change its format to same as i've given input. InShort i want to parse a string to date and it should convert that String to date with exactly the same format.

JSF :: Primefaces Calendar Component Passing Incorrect Date Format

Jan 27, 2015

I am using the calendar component of the primefaces and I am using the attribute pattern="MM/dd/yyyy.But when I print the values in my MBean along with the selected date event the timeZone (i think) is printed as Sun Mar 29 00:00:00 IST 2015 I do not understand why its printed even though I have set the pattern.Part of my code :

XHTML

<p:calendar id="singleDaySchedule" value="#{scheduleMBean.exactDate}"
showOn="button" pattern="MM/dd/yyyy" required="true" requiredMessage="Date is Required"/>
<p:commandButton value="Submit" update="form" actionListener="#{scheduleMBean.showSchedule}" icon="ui-icon-check" />

[Code] ....

I found out that we need to use <f:convertDateTimePattern> instead of how I am using currently.But I am not able to figure out where to use

<f:convertDateTimePattern>

Read Date From File / Calculate And Then Displays That Data In Table Format On Screen

Apr 22, 2015

The intent of the code is to read date from a file, does calculation and then displays that data in a table format on the screen. Then creates another file with those values:

Reads file: Beginningbalance.txt
Displays Data with calculation
Creates a file called "Newbalance.txt" with the following values:

111
251.41
222
402.00

With the way the code is written I can get it to create the file but it only displays one of the customers (111). I know that I need to create a loop but I am not sure how to build that. I tried creating another while loop and changing it to outFile but that was without success.

import java.io.*;
import java.util.Scanner;
import java.text.DecimalFormat;
public class Output {
public static void main(String[]args) throws IOException {

Working With Gregorian Dates And Object Date?

Feb 10, 2014

I have two classes - a reservation class & a main class. Essentially, I want the user to enter two dates: an arrival and departure date. From the two dates, I will do a calculation (num days & price). I am having trouble finding a way to let users enter the (preferably in int, but that wasnt working),use getTime() to convert it from a calender to a date object. Then I want to use the dates to do a calculation. In addition, my constructor is being funky.

package hotelreservation;
import java.util.Date;
import java.util.Calendar;
import java.math.*;
//import java.text.*;
public class Reservation

Exception In Thread Main - Cannot Format Given Object

Apr 16, 2014

I am working on a program that will allow a user to input grades for a class of four students who have taken two tests. Based on the grades entered, the program will calculate the averages of the two tests for each student and display it along with their respected letter grades.

Now I can get the program to compile successfully, but after inputting the grades in, I get the error message saying that it cannot format given object as a number. I am using 4 arrays to execute this program and maybe that's why I'm having the trouble? I'm not sure because I am still fairly new at this stuff and can't sen to resolve it.

I was having problems for a while and then finally got excited when I got it to compile without any errors and now I'm getting an error inside my program. All I need to do is format the numbers of the grades into something like: 000, and each of the averages as 000.0. I understand how to do it because I have done it in another program I've done in the past. I just don't know how to fix this error that is coming up.

here is my code:

import java.util.Scanner;
import java.text.DecimalFormat;
public class TestAverage
{
/**
* A program that will store and process 2 test scores for a class of 4 students.
* The program will prompt for the test scores as shown above in the sample run.
* After all the data is entered,the program will display the score for test 1, test 2 .
* The average of the 2 tests and the letter grade for the class for each student in a tabular format.
*
*
