desired effect is that every month on the 10th , the 15th , the 21st automatically run test () method .
please god pointing, I white , preferably with example code. grateful ! ! !
------ Solution ---------------------------------------- ----
that is upgraded , the method can not be used , and you like to try using 1.5.1 jar
------ For reference only ----------- ----------------------------
Timer timer = new Timer();
timer.schedule(new MyTask(), 1000, 2000);
with a timer
an implementation method is executed every point , judgment is not to be performed on the implementation of this day is not executed contrary
Another is set next execution time, execution continues after the expiry of this method is called to set the next
------ For reference only ------------ ---------------------------
The easiest way is that you get the current date , and then put out to compare the interception day , match, call timer .
------ For reference only ------- --------------------------------
I can not meet the requirements of this Yeah ! I run every month on the 10th next month 10 finished running again .
This is the number of seconds after you run MyTask (), then every number of seconds to continue running MyTask ().
can not be determined to run automatically every month on the 10th MyTask ().
------ For reference only ---------------------------------- -----
that I executed in this MyTask (), or after the 10th of each month to continue running MyTask ()
------ For reference only - --------------------------------------
two programs closer look look , the first program , performed daily , if it is the 10th on the implementation of test not just skip
The second program , the 10th execution , after the implementation of the next month on the 10th to set execution , after the implementation of the next month on the 10th next month on the 10th execution settings so that every month on the 10th after execution will set a timer to perform next month on the 10th , do I say I do not know whether you can understand ?
------ For reference only -------------------------------------- -
this on your own for a month on the 10th and the 10th of next month, the number of seconds , and then set down on the line ah
------ For reference only --------- ------------------------------
can use quartz timing tasks , which is particularly suggest you to check all check with CraoTrigger class , Gron expression can control the execution time for example "0 15 10? * 6L" represents the last Friday of every month 10:15 executive

quartz timing tasks , do not really understand , can you give examples ! !

need to import a few jar package
commons-logging.jar
log4j-1.2.13.jar
quartz-1.5.1.jar
quartz-all-2.1.7.jar
me this is temporary Minato , non-standard should be unified with the 1.5 version of the
