Cant get the current hour

Hi i am trying to get the hour of the current time using the calendar class and when the time is on the 12th hour, the hour returns 0 instead of 12.
here is my code below:
//Update the time
                    calendar.setTime(new Date());
                    hour = calendar.get(calendar.HOUR);

http://java.sun.com/j2se/1.4.2/docs/api/java/util/Calendar.html
* Field number for <code>get</code> and <code>set</code> indicating the
* hour of the morning or afternoon. <code>HOUR</code> is used for the
* 12-hour clock (0 - 11). Noon and midnight are represented by 0, not by 12.
* E.g., at 10:04:15.250 PM the <code>HOUR</code> is 10.
* @see #AM_PM
* @see #HOUR_OF_DAY

  • GregorianCalendar - getting the current date

    Hi,
    Have any of the Calendar classes been changed in version 1.5. I'm trying to get the current date and time in an application, to add to filenames when they are backed up. In java 1.4 the following code was sufficient to get the information required:
    GregorianCalendar cal = new GregorianCalendar();
    filename = "C:\\Program Files\\Apache Group\\Apache2\\www\\test\\htdocs\\backups\\";
    filename += theFile;
    filename += "=" + getUser() + "=" + cal.get( Calendar.HOUR_OF_DAY ) + "_" +
         cal.get( Calendar.MINUTE ) + "=" + cal.get( Calendar.DAY_OF_MONTH ) + "_" +
         ( cal.get( Calendar.MONTH ) + 1 ) + "_" + cal.get( Calendar.YEAR );
    I'm writing another app using the same code and SDK 1.5, but it's returning the same values every time.
    Cheers
    Matt

    I wrote a small program to test the Calendar object on my system:
    import java.util.*;
    import java.awt.event.*;
    import java.awt.*;
    public class Tester extends Frame implements ActionListener
         public Tester()
              javax.swing.Timer timer = new javax.swing.Timer( 1000, this );
              timer.start();
              setSize( 400, 400 );
              show();
              addWindowListener(
                   new WindowAdapter()
                        public void windowClosing( WindowEvent e )
                             System.exit( 0 );
         public void actionPerformed( ActionEvent e )
              Calendar cal = new GregorianCalendar();
              System.out.println( "Time: " + cal.HOUR + ":" + cal.MINUTE + ":" + cal.SECOND );
         public static void main( String args[] )
              Tester t = new Tester();
    This repeatedly outputs:
    10:12:13
    I tried this with Calendar and GregorianCalendar. Both of them do not seem to work. I'm not using the same Calendar object, or outputing in the same second....

    Hello pipin23,
    If you have a 2G iPod, you will not be able to update past 4.2.1.  Only 3G and 4G iPod Touch models can upgrade to 4.3.

  • How to get the current filename and & or path

    How can I get the current path or filename?
    I didn't really find any answers in the net. this.path or app.path were suggested but I couldn't get it to work.
    Thanks in advance for your answer!
    Livecycle Designer ES 8.2.1.3144.1.471865

    Hi,
    event.target.path.toString();  will give the full path including the filename.
    event.target.documentFileName.toString();  will give the filename only.
    Good luck,
    Niall

  • How to get the current path of my application in java ?

    how to get the current path of my application in java ?
    thanks

    To get the path where your application has been installed you have to do the following:
    have a class called "what_ever" in the folder.
    then you do a litte:
    String path=
    what_ever.class.getRessource("what_ever.class").toString()
    That get you a string like:
    file:/C:/Program Files/Cool_program/what_ever.class
    Then you process the result a little to remove anything you don't want:
    path=path.substring(path.indexOf('/')+1),path.lastIndexOf('/'))
    //Might be a little error here but you should find out //quickly if it's the case
    And here you go, you have a nice
    C:/Program Files/Cool_program
    which is the path to your application.
    Hooray

  • Hi, I have a late 2011 MacBook Pro but cant get the mirroring function to work with Apple TV.  I've got the most recent Software 10.7.5 but cant see the mirroring icon or turn this on.  I'm able to mirror from my Ipad but not my Mac, any thoughts?

    Welcome to the Apple Support Communities
    AirPlay Mirroring is supported on your Mac, but it needs OS X Mountain Lion (10.8). See > http://support.apple.com/kb/HT5404
    You have two possibilities:
    1. Make a backup, open App Store and purchase Mountain Lion to upgrade to this OS X. Then, you will find the AirPlay Mirroring icon at the top right of the display, on the menu bar, or on System Preferences > Displays.
    2. Keep OS X Lion and use AirParrot > http://www.airparrot.com
    Both options work properly, but I recommend AirPlay Mirroring as it doesn't need a third-party program

    just started a new apple tv and also started using an iMac . I have itunes on the iMac but i cant get the apple tv to sync or find any settings to do so ! How can I get the iMac and apple tv to sync the itunes ? i have a internet connection between them , I have signed in to the itunes store on the apple tv and it shows that the apple tv is sharing my library from the IMac , but it wont sync and the apple tv has no content !

    Welcome to the Apple Community.
    The Apple TV (with the exception of the Apple TV 1) does not sync, it streams everything from your library on your computer or from the internet.

  • HT204291 cant get the airplay icon on my iphone 4.

    I've tried all recommendations in troublshooting but still cant get the airplay icon on my iphone4, I can use the remote app, so its definately connected, any ideas?

    Responses can only be as helpful as the details provided.  What are you trying to setup an AirPlay connection to?  Did you enable AirPlay on that device(s) and create an Id?  Did you enter that id into your iPhone?  Did you do any of the steps to setup AirPlay? 
    And the Remote app using HomeSharing which only connects to iTunes and iTunes connects to the other devices.  It has nothing to do with AirPlay.  So that does not really mean anything.

  • How to get the current user name of the host who is occupying a specific VM?

    I'm developing a winform app with c# code to manage Hyper-V. I need to remind someone if he/she would take a VM which has already been occupied by others.
    Is there any powershell cmd or WMI interface to get the current user of a specific VM?
    Thanks!

    Hiya,
    from cmd there are quser(Query user) and qwinsta(Query Session)
    which should give you that. Don't know how you can incoorperate that in C#, but that should give you something to work with :)

  • How to get the current page URL

    HI All
    I am working in oracle apps 4.0
    I have one page called history in that i have one page item called Application url. My application id is 122 but its a copy of application 106
    How to get the current page url for the page item.
    Any steps should be help ful
    Thanks & Regards
    Srikkanth.M

    I'm not 100% clear on what the requirement is from the description, however it does sound like you are making things unnecessarily complicated.
    If you want permanent/ID-independent links then use application and page aliases.
    so here we used to display the url like this: <tt>{noformat}http://81.131.254.171:8080/apex/f?p=122{noformat}</tt>
    Do you mean that the URL is displayed like that? If so that doesn't seem particularly helpful. How is anyone supposed to know what it is?
    There are many ways to provide links in APEX&mdash;including lists and nav bars.
    Where the link is to another resource located on the same server (such as another page in the same app, or a different app in the workspace), relative addressing can be used, making it unecessary to include scheme, domain and port information in the URL. For example, if the page to be linked to has a page alias <tt>ABOUT</tt> in an application with alias <tt>UNITY</tt>, and the apps share an authentication scheme/cookie to permit shared sessions, then the link URL is simply
    f?p=UNITY:ABOUT:&APP_SESSION.

  • How to get the "current date" in the BEx?

    Hi all,
    I need to get the "current date" in my Bex report in order to make a comparison. I know there is a "How to" which shows how to get the current date via a User Exit, but I didn't find it. Could you please help me?
    Thanks

    1. Create a  New Formula in Key Figures structure
    2. Give tech name and description and Select "New variable" option
    3. Next screen will launch Variable Wizard -> create a new variable with replacement path as processing type
    4. in next screene  select the date characteristic that represents the first date to use in the calculation (From Date)
    5. In the next  screen select Key in the Replace Variable with field. Leave all the other options as they are
    6. In the next Currencies and Units screen select Date as the Dimension ID.
    6. Save variable
    repeate the Above steps to create another variable (To Date)
    and now you can use these two new replacement path variables in your new formula.
