Using TimerTask to run a process 3 times (one at 0 seconds, one at a specified time , and another at a third time)

I'm not sure if you can specify timer tasks using the same timer with 3 different times. Perhaps you can simply write your own thread and do the task (and use your own time for sleeping). Something like:

int[] durations = { 500, 100, 200 } ;
int[] processes = { "Process1", "Process2", "Process3" } ;

In your run () method:

int count = 0 ;

while ( count < durations.length )
{
  Process p = Runtime.getRuntime ().exec ( process[count] ) ;
  p.waitForExit () ;
 // do any other stuff you want to do
  Thread.sleep ( count ++ ) ;
}

System.out.println("Process 1 is done");

Then check out the print out message on the console.

If I just wanted to have it run within one thread and not stop it

and only execute only under on type of condition that once set wont do it

public static void main(String args[])
{
while (threadtoggle=true)
{
 if scenario is true
  run method



}

}

Scenario stil true wait said time

run method

Scenario true

Run method


continue now that it passed or fail out (threadtoggle =false)



}

}

  Timer timer = new Timer();
    timer.schedule(task1, new Date());    // execute now
    timer.schedule(task2, time1);             // execute at time1
    timer.schedule(task3, time2);             // execute at time2

In each of the tasks defined above as objects has shown, you will need to check if the scenario is still true or not, at the starting of the method.

Sorry if I wasn't clear in my previous posting. Don't particularly like Mondays!  I increased the points to this one too

This is basically what I want to do

have only one timer thread...

want to have the three task try if a scenario is present if not do other processing.  Is there a way to capture the result
of a scheduled task if it fails ===> timer.schedule(task2, time1);             // execute at time1
Should I try cand catch them to do that??????  



Timer timer = new Timer();
testboolean is false

while (logic=true)  // want this as a constant process….
{

     while (testboolean is false) //to test if scenario is present
      {

       
         boolean testboolean false
{  
timer.schedule(task1, new Date());    // execute now
}
       

process completes
testboolean true

process fails
testboolean false
try again (testboolean still false)
{
timer.schedule(task2, time1);             // execute at time1
}

process completes
testboolean true

process fails again
testboolean false
try again
{
timer.schedule(task3, time2);  
}

completes
testboolean true


fails for the thirs time
testboolean still false
sleep (1day)

}

other processing

}

If you want just one thread and you don't want to schedule tasks in the future, then I would say you don't need a Timer but you can do it in a simplified manner by using your own thread.

Actually mayankeagle,  I want to schedule the two other tests at different times...  Or should I just use sleep?  say sleep for 5 seconds...  try again... sleep for 15 minutes try again....   sleep for a day.....  start over....


Thanks

Thanks guys

Think I will just use my on thread and sleep.  If I created a timer or a timertask I'd have more than one thread....  Was already told not to use a TimerTask too.

Thanks alot
