Why is it so confusing to get the time

timefrom java.util.Calendar.getInstance you can get a Calendar object which contains current date and time.
you can use java.text.SimpleDateFormat to get the string which formatted the date or time.

  • TableCellEditor that Supports Both Date and Calendar

    Hi,
    I'm trying to write a TableCellEditor that supports both the Date and Calendar Classes (i.e., my table could have either Dates or Calendar objects, and I want this cell editor to work seamlessly with either one).
    Here is a simplified version of my code:
    public class DateCellEditor extends AbstractCellEditor implements TableCellEditor {
    /** The editor component. */
    private DateChooser editor;
    private Calendar cal;
    public DateCellEditor() {
    super();
    editor = new DateChooser();
    cal = Calendar.getInstance();
    public Object getCellEditorValue() {
    cal.setTime(editor.getDateValue());
    return cal;
    public Component getTableCellEditorComponent (JTable table,
                                                                                                                            Object value,
                                                                                                                            boolean isSelected,
                                                                                                                            int row,
                                                                                                                            int column) {
    if (value != null) {
    if (value instanceof Calendar)
         editor.setDateValue(((Calendar)value).getTime());
         else if (value instanceof Date)
         editor.setDateValue((Date)value);
    return editor;
    As you can see, I've already modified getTableCellEditorComponent to accepted object of class Date or Calendar. My problem arises in the getCellEditorValue method. How do I know which type of object to return? In the code sample above, I'm returning a Calendar object, but I'm not sure how to code this method to return either Calendar OR Date.
    By the way, editor.getDateValue() returns a Date object.
    I could easily write two separate TableCellEditors, but I would prefer a more elegant solution. Any ideas?
    Thanks!
    Karen Prengaman

    If you really must have both objects and don't want to convert one into another, you could add a function like
    setMode(int modetype) {}
    where modetype is either DATE or CALENDAR, and then return the set type when the user calls getValueAt

  • Overview of Dates and Calendar

    hi,
    does anyone know some good links that explain what is going on with Date and Calendar etc..
    It seems quite complicated - is there any docs on the general idea/framework? (and why things have been deprecated etc..)
    I don't know anything about different world calendars, but theres lot on the web, so its more the java specifics I'm interested in!
    thanks,
    asjf

    Don't use Date at all, use Calendar instead (unless you need to use dates in databases). What parts of the Calendar docs aren't clear? The general idea is each instance of Calendar represents a point in time, with methods to change and retrieve various datetime fields.

  • Any Expert on Date and Calendar????

    Once I set my own calendar .. why it's not keeping my calendar and printing the date and time onwards from my set date time...
    I just print only one time the date/time but later in my thread, it prints OS date and time....?
    Any Ideas??

    Chuck, Thanks for you reply..
    But your solution would 'nt work if some one change the system date..
    I need some solid solution....
    If you do not understand what i am say then do this

  • Ical or Calendar (or whatever) doesn't detect dates and calendar names anymore!

    Hi everyone.
    I used to have a weekly email created with automator and ICal, parsing a specific calendar by its name, and creating
    a list of events occurred in the week (monday to sunday) to send. I used an automator ical alarm for this (now called automator CALENDAR alarm???).
    It worked like a charm.
    Enter Mavericks.
    It's doesn't work anymore.
    Couldn't open the file. So I set to edit it and re-create it, but to no avail.
    I've tried to debug it, by going down to basic actions and their output, and I found out that for example:
    - A one action workflow, find calendar events, with date starting this week, doesn't work!
         No output, when I have pretty many events occurring in the week.
         It doesn't work even if I change the condition (today, or 2 days from now etc...)
    - Another single action workflow (still for testing purposes), filter calendar where title contains any calendar name returns nothing, while there are many calendars in the app!
    Can anyone help?
    Did you experience the same problems?

    Any solution on this problem? I'm experiencing the exact same problem on our 2 GHz iMac Core 2 Duo.

  • Date and Calendar object

  • Where do Date and Calendar get the current date?

    The server's time is correct, but my Java application is one hour fast... Why could that be?

    Maybe because Java has a different notion of "local time zone" than whatever you use to check the time.
    Try checking the local timezone that Java thinks is in effect and compare this with whatever the OS provides.
    A common case seems to be that Java has more up-to-date timezone data than the OS and Java is actually true.
    And: you could easily make a mistake by converting Date/Calendar/... around an mess up the timezone information (don't ask me how exactly, but I've seen it before).

  • How can I get Chinese characters in the date and calendar?

    The other night I was using a friend's Japanese iBook. I noticed that she the day displayed with a Chinese character in the menu bar and in the calendar widget (e.g., Her clock said 月4:27 instead of Monday 4:27), but her interface was in English (no Japanese menus).
    How can I set the day to display with a Chinese character?

  • Question on Dates and Calendar

    i need to find the number of days between 2 given dates. For example, the number of days between Nov 29th 2006and Dec 3rd 2006 is 4. The number of days between Nov 10th and Nov 15th is 5. How do i do this? Is there an api for doing this?

    No API does this; by using the Claendar and related classes it's easily calculated. See these:

  • Financial Reporting - Derived data and calendar periods

    I have two questions with Financial Reporting
    1. I have a P&L report that shows the full 12 months. FR displays the derived data of the next actual period even if there has been no consol. It therefore looks like all the data has been reversed to zero. Is there a setting to stop FR from displaying derived data?
    2. The application has a June year end. We want to display in the report titles the months based on their calender year rather than the fiscal year. This means that for Sept we want Sept 2011 to display, not Sept 2012 that will come from the Year dimension. Is there a function to handle that?

    The answer for this might be the VIEW dimension.If u have taken YTD please change it to Periodic and give a try.

    While creating application profile we have a choice to select the years or just look into application settings.I am not sure just give a try.

  • Date and Calendar Classes

    Well, I'm trying to do a program which valildates a Date given by the User (Does it matter if it's an example using the console, or not?? 'Cuz I'm using it on a Swing application). I WAS using
    date's constructor:
    new Date(y, m, d); but it doesn't do a thing, I can make a new instance
    of Date EVEN if it's February 31st (WHICH IS NOT RIGHT!!!)... how can I do it??

    Im not really sure if I understand what your asking, but I thnk that in the constructor you need some stuff like
    if ( m > 12){
          m = 0
    if ( m == 2 && d > 28 ){ // that would be just for febuary
          d = 0
    }But you probobly would have to do that for every month.
    hope this helps

  • For a few months now my ical keeps jumping back and forth.  It's very hard to use my calendar as it doesn't open on today, it may stay a few seconds and then it goes backwards to random dates and forwards.  It doesn't sit still so I can see what I have on

    My iCal is driving me nuts.
    It won't sit still when I am looking at my calender.  I try holding it still with one finger, two fingers and it just moves.  It jumps to random dates and I have no confidence in it any longer.   I use my calendar all the time and this just isn't good enough.
    I have gone into the apple store and they said they hadn't seen that before.  It did it while I was there.  They restored the phone and it didn't make any difference.
    I have turned the calendar off in settings - mail - icloud - deleted and then turned back on again.  It didn't help.
    I put the Google Calendar app on in the hopes I would have a calendar that wouldn't frustrate me and it is so slow in responding, I have deleted it.
    I see online that many others are having the same problem with their iCal. 
    It would be great to know the solution.
    Please help

    Hey everyone in Apple world!
    I figured out how to fix the flashing yellow screen problem that I've been having on my MBP!  Yessssss!!!
    I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
    I followed the instructions on this page and here's what I did:
    Resetting NVRAM / PRAM
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process.  Since I did that, my MBP boots up just like normal.  No flashing yellow screen anymore!!   
    (Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
    Let me know if this works for you!

  • How can I get missing contacts, notes, calendar dates and reminders that are just on my old iphone onto the iCloud for transfer to my new iPhone upgrade?

    Dear wise & wondeful people:
    How can I get missing contacts, notes, calendar dates and reminders that are just on my old iphone onto the iCloud for transfer to my new iPhone upgrade? Half of my contacts, notes, ect. were on my iCloud so have happily moved to my new iPhone but the rest are completely resistant. For example, on my iCloud I have 14 missing contacts starting with the letter A alone, however they are happily viewable on my old iPhone 4S and won't budge over into the iCloud.
    There are also 3 notes missing yet still acessible on my onld iPhone 4S, the list goes on.
    Your help would be most appreciated. Thank you so much.

  • When I create a calendar, in iphoto 8, I had an information pane lower left corner with date and time of the picture. Can it possibly be that the iphoto developers forgot about that in iphoto 9? This was very helpful when placing images according to date.

    Today I updated to the latest iphoto version. The update itself went smooth and nice as one is used to from Apple. But when I wanted to finish my already started calendar, I have encountered two problems. The first is that I can't view the aperture library anymore directly from iphoto. Instead I have to open the iphtoto library in aperture but then my calendar isn't there. So now I have to copy images back and forth. No problem.
    However, the old iphoto had a small information area in the lower left corner which was very nice to place images on an exact date. This seems to be gone...?? Really? How am I supposed to sort images according to date and time when I have to back to the library view every time? That's not very convenient..Or am I missing something?
    Thanks for ANY help!
    Patrick

    The first is that I can't view the aperture library anymore directly from iphoto.
    THat is exceeding strange since iPhoto '08 could not open or share an Aperture library - that ability was first introduced in iPhoto '11 - with the latest version of iPhoto and or Aperture you can open the same library with either application - http://support.apple.com/kb/HT5043
    In the current version of iPhoto the photos are sorted by date in the film strip - I've not recently done a calendar so do not remember the specifics -

  • How do I get my contact and calendar data brought back from iCloud and reinstated in Outlook on my PC?

    I just accepted Apple's kind invitation to synchronize my Outlook contacts and calendar with their iCloud storage.  I foolishly accepted the invitation only to discover that iCloud didn't synchronize my data but stole it without any warning as to what it was going to do.  Does anyone know how I can recover my data and put it back onto Outlook on my PC?  I need to be able to access it when I'm offline, which I can't do if it's all hidden away in the iCloud.  Besides that, any new contacts that I add don't automatically get added to iCloud.  The whole arrangement makes a mockery of the concept of "synchronization". 

    Your data is in Outlook, in the iCloud account instead of the local (Personal Folders) account.
