Question

for(int i = 1; i < 10000; i++) {
Command nextCommand = getNextCommandToExecute();
}

I want to run the above program for 60 minutes. So instead of for loop I need to do something like-

long startTime = System.nanoTime();

    do{
    Command nextCommand = getNextCommandToExecute();
    } while (durationOfTime is 60 minutes);

But I am not sure, how should I make this program to run for 60 miniutes.

Answer 1

try the following:

long startTime = System.currentTimeMillis();
long endTime = startTime + (60*60*1000);

while(System.currentTimeMillis() <= endTime) {
    Command nextCommand = getNextCommandToExecute();
}

One drawback with this method is if the Command you are trying to execute runs past the 60 minute timer or never finishes at all. If this behavior is not allowed, you are better off implementing a thread that interrupts whatever thread is running this loop.
