datetime - How to set Time property in Java using Joda-Time -

i want set hour, minute , seconds in joda-time. when set it's not changing property.

here code:

import org.joda.time.datetime; public class jodaakbar  {  public static void main(string args[])  {      datetime dt = new datetime();     system.out.println("before:"+dt);     dt.hourofday().setcopy(5);     dt.minuteofday().setcopy(20);     dt.secondofday().setcopy(0);     system.out.println("after:"+dt);  } } 

here output.

before:2015-04-01t11:01:38.277+11:00 after:2015-04-01t11:01:38.277+11:00 

i getting same output. what's happening wrong here?

edit:

basically, want similar shown in below code. below code doesn't work 24 hour format, switched joda-time.

 calendar cal = calendar.getinstance();  cal.set(calendar.hour, 13);  cal.set(calendar.minute, 25);  cal.set(calendar.second, 0); 

joda-time objects immutable. word "copy" in setcopy telling doesn't set these fields directly, instead creates copy of datetime field modified.

a quick fix is:

dt = dt.hourofday().setcopy(5); dt = dt.minuteofhour().setcopy(20); dt = dt.secondofminute().setcopy(0); 

a more fluent approach chain several with methods together:

datetime dt = new datetime()     .withhourofday(5)     .withminuteofhour(20)     .withsecondofminute(0); 

or single withtime call:

datetime dt = new datetime().withtime(5, 20, 0, 0); 

by way, java 8 introduces new java.time package inspired joda-time. joda-time web site recommends, "from java se 8 onwards, users asked migrate java.time (jsr-310)."
