Transform Simple Date Format - Get Calendar Date
Apr 4, 2015Given 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...

Adding Days To A Calendar To Make End Date
Oct 25, 2014I need to add a few days to make an end date (for instance the start date is the first date selected, and then the end date is x amount of days after that... I think I should be using the add() method but I am not quite sure of where or how to do so)...
Java Code:
//Get an instance of Calendar and DateFormat class, and get current date from the system using OnClick method

Implementing Gregorian Calendar Into Project - Date Formatting?
Sep 22, 2014I'm a Java beginner and I'm having issues implementing Java's GregorianCalendar into my project. I'm writing to specific test code that passes arguments into an instantiated GregCal class. My problem is that I'm not sure how to pass the arguments through to my constructors and methods, or if I'm even supposed to do that at all. Date formatting is another issue, but I'll be glad If I can just get the dates in and back out. Here is some of the code:
Test code:
// Create a Student using the default constructor
Student newStudent = new Student();
GregorianCalendar dateOfBirth = new GregorianCalendar(75,7, 3);
newStudent.setDateOfBirth(dateOfBirth);
GregorianCalendar dateOfGraduation = new GregorianCalendar(90, 6, 10);
newStudent.setDateOfGraduation(dateOfGraduation);
Setter:
public void setDateOfBirth (GregorianCalendar dateOfBirth){
this.dateOfBirth = dateOfBirth;
}
I know that's not much to work with, but that's exactly my issue. I can't seem to find a reliable and UNDERSTANDABLE tutorial for java.util.GregorianCalendar anywhere. All of the existing documentation is beyond my grasp at this point. I'm assuming I need to declare and initialize MONTH, DAY, YEAR variables somewhere in order for the arguments to be passed through correctly. I'm just not sure where or how.
JSF :: Primefaces Calendar Component Passing Incorrect Date Format
Jan 27, 2015I 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" />

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>

View Replies View RelatedHow To Set Time For Calendar
Mar 7, 2014I would like to set a specific time for a Calendar instance. My below code will set a time one minute ahead of the current time, and format it to ISO8601 standard.
Java Code:
Calendar reminderDate = Calendar.getInstance();
System.out.println(dateFormat.format(reminderDate.getTime()));
reminderDate.add(Calendar.MINUTE,1);
SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String finalReminderDate = sdf1.format(reminderDate.getTime()); mh_sh_highlight_all('java');
I now want to set another variable(deadlineDate), but to a specific time, say 5 minutes ahead. I would like to hardcode this in so I dont want it to change as a result of getting the instance of the Calendar(which sets it to the current time)
Essentially I am trying to regenerate the above code every minute and increment itself each cycle until it reaches the deadlineDate, which is a fixed datetime.
How can I do this?

String To Calendar Time
Feb 9, 2014I'm having an issue with this little bit of conversion. I'm converting a string (_dateString) into a Calendar time. I am using DateFormat and SimpleDateFormat to accomplish this task. Everything seems to be working great, except for it figuring out whether it is AM or PM. According to SimpleDateFormat (Java Platform SE 7 ) I am using "aa" to get my AM or PM marker. How come in my output then, it believes it to be 4:45 am instead of 4:45 pm? Hour of Day should return the 24 hour clock, which should show 16 instead of 4. I have posted the output below my code.
Java Code:
import java.text.*;
import java.util.*;
public class Time{
static String _dateString = "08 Feb 2014, 4:45pm";
public static void main(String args[]){
Calendar cal=Calendar.getInstance();

Output:
Java Code:
Today is Sat Feb 08 04:45:00 EST 2014
Year: 2014

Day of Month: 8
Day of Week: 7

Is Calendar Mutable - What The Value Was Initialized With
Jun 9, 2014I have a field that initializes a Calendar object:
Java Code:
private Calendar zeroPointTime = zeroPointTime();
private Calendar zeroPointTime(){
int year = 2000;
int month = 0;
int date = 1;
int hourOfDay = 0;
int minute = 0;
Calendar calendarTime = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
calendarTime.set(year, month, date, hourOfDay, minute);
[Code] ....
But other times I need to reference what the value was initialized with, not offset values added to it with various function calls.
When I use add() will that modify zeroPointTime? If so, how can I add seconds to a Calendar object without altering its value?

Displaying Calendar For Each Month Of Given Year / Day
Feb 15, 2009I'm working on a program that prompts the user to enter the year and first day of the year and displays the calendar table for that year on the console.

I have written the program and solved the problem for the most part. Only, I'm having terrific difficulty getting the output to properly format. I'm *almost* there. I'll post my program below and then output.

Printing Gregorian Calendar Default Constructor?
Sep 20, 2014I am having trouble with getting output to be what I want. I can get the output when a user enters their values for month, day and time using a scanner object and they print correctly, but what I want is before they input values, to display the current date. Here is a snippet of what I am working with *these are in two separate files, the first has all the variables etc, the second has the main method.
In one java file:
Java Code:
private int numOfGuests, month, day, year;
private GregorianCalendar eventDate = new GregorianCalendar();
public Event()
{
this("not assigned" , 0, new GregorianCalendar());
}
public int getDay() {

This gives me 0-0-0 as a result instead of current date.
JSF :: Event Calendar With Component P - Schedule Of Primefaces
Jun 20, 2014I have a problem to display a popup with the information of the registered event. I would like the user to hover over a particular event exhibited only the description of the event without having to click on the event to view information. I would like to make an ajax request to that was displayed a popup.
But do not know how to implement jquery and javascript. Well, I am new to programming. My code that generates the schedule is as follows:
<p: schedule value = "#{bean.datamodel}" widgetVar = "sheldule" locale = "en"
rightHeaderTemplate = "prev, next" leftHeaderTemplate = "today" centerTemplate = "month"
id = "events"
tooltip = "true">
<p:ajax event="dateSelect" listener="#{bean.onDateSelect}" update="eventsNew" oncomplete="eventDialog.show();"/>
<p:ajax event="eventSelect" listener="#{bean.onEventSelect}" update="eventsNew" oncomplete="eventDialog.show()"/>
</ p: schedule>
In my Bean have methods that make the selection of date and event. Have I configured the option of setEditable to true. Ajax function, jquery or javascript to show the popup containing only observation and event date. And looked at the documentation of primefaces and not found any implementation to solve my problem.
