DATE in JAVA

[karthikeyan_raju]

hi,
my program needs to run a particular process only between say, 9 am to 5 pm every day. and if the system time is not between this, the if shud not be executed.

how to obtain such a functioanality. I would prefer the start time and end time to be configurable , to be picked up from a properties file.

any clues..??

Calendar calendar = GregorianCalendar.getInstance();
System.out.println(calendar.get(Calendar.HOUR_OF_DAY));

Unix or Windows (or other)? I believe that unix OS has this timer functionality built in to it, and it could possibly even start up your app each day at a certain time.

Also, does your program need to use a java.util.Timer?

there are 3 threads running at the moment.. all kicked off from the same java class..
with sleep times configured.. so once the thread.sleep() is invoked, it sleeps for the specified time..

all three threads function the same way..

but i need one of these threads to run between a particular duration of the day.. and rest of the time.. run/sleep.. but shud not perform the functionality that is expected out of it..

using windows OS.. the entire program is goin to be deployed on unix but.. is it possible to control jus one thread in UNIX..??

the whole program as such will be running based on a particular time line..

public void run()
{
   while(running)
   {
      ...
      Calendar calendar = GregorianCalendar.getInstance();

      int hour = calendar.get(Calendar.HOUR_OF_DAY);
      while( hour <9 || hour >= 17 )
      {
         if(!running)
            return;
         try {
            sleep(1000); //or some other time amount
         }catch(Exception e) {}
      }
      ...
   }
}
