hour

There is a JTabbedPane In my Swing program. When user clicks on a tab, the program takes a while to get the data and process the results, then shows the results in the selected tab. How can I display a hour glass, or something of that effect so that user knows it's processing data? Not to click on the tab again before it finishes it job. A JProgressBar (possibly in indetermiante mode) sounds right - put that on the tab until the data has been fetched. A well-designed UI shouldn't force the user to wait for long-running tasks to complete and instead allow them to do something else inbetween.

Fiddle: http://jsfiddle.net/bnsex/1/ I want to use 12 hour clock for this code... $(document).ready(function() { setInterval( function() { var hours = new Date().getHours(); $(".hours, .hour").html(( hours < 10 ? "0" : "" ) + hours); }, 1000); }); ​ Your help is much appreciated :D You can achieve this using the modulus % operator, which finds the remainder of a division operation. For example, 11 % 12 and 23 % 12 both equal 11, like a 12-hour clock would portray. var hours = new Date().getHours() % 12; if (hours == 0) { hours += 12; } http://jsfiddle.net/ph7Vf/ Try with this: hours = (hours <

I need to get / print on command line every full hour of every day of a given year, e.g. 2011 but I am struggling to code it in Java. Has anybody ever coded this issue? This should work: final DateFormat df = DateFormat.getDateTimeInstance(); final Calendar c = Calendar.getInstance(); c.clear(); for (c.set(2011, Calendar.JANUARY, 1, 0, 0, 0); c.get(Calendar.YEAR) == 2011; c.add(Calendar.HOUR_OF_DAY, 1)) System.out.println(df.format(c.getTime())); Notice, for example, this subtlety in the output: Oct 30, 2011 12:00:00 AM Oct 30, 2011 1:00:00 AM Oct 30, 2011 2:00:00 AM Oct 30, 2011 2:00:00 AM

I would like to extract the hour from a POSIXct time in R, but retrieve the 2 digit answer. For example, test=as.POSIXct("2015-03-02 03:15:00") test [1] "2015-01-02 03:15:00 GMT" month(testing) [1] 1 hour(testing) [1] 3 The results give the relevant month and hour, but I would like to see 01 and 03 instead of just 1 and 3 . Try to do this: strftime(test, format="%H") to extract hours and strftime(test, format="%m") for month 来源： https://stackoverflow.com/questions/35227648/extracting-2-digit-hour-from-posixct-in-r
