Java Infinite very long loop

I have to do a Java infinite loop but 1 loop would last 24 hours. What is the best way to do it? How could I kill it? Pause and resume it?

Your question does not really explain what you are trying to do, but I will try to give you some tools to work with.

To run a single loop or a predetermined amount of loops asynchronously, you may achieve what you need with Threads.

If you need more control like how many tasks can be running at the same time, you may use a Thread Pool implementation. This is helpful especially if you don't know how many tasks have to be started and need to restrict memory usage.

I hope this helps.

"I have to do a Java infinite loop but 1 loop would last 24 hours. " As mentioned if the loops end at some time even if large its not infinite. So, do you mean infinite loop only or the the loop ending 24 hrs? A simple infinite loop is

do{
  //do your stuff
} while (true);

How about just sleeping for 24 hours?

Thread.sleep(24*60*60*1000);

You can use the Timer class with the method:

void    schedule(TimerTask task, Date firstTime, long period)

Perhaps a while loop, where you check the elapsed time in the loop condition? This may get pretty expensive if the loop body is short, however.
