running loop for 5 minutes

Question

I have a requirment to run a while loop the 5 min. I looked for the timer api but I could not found to do this. Can any one provide a code snipet for this.
Thanks

Answer 1

This loop will run for 5 minutes. It will not be effected by changes made to the computer's date/time (either by user or by NTP).

long endTime = System.nanoTicks() + TimeUnit.NANOSECONDS.convert(5L, TimeUnit.MINUTES);
while ( System.nanoTicks() < endTime ){
  // do whatever
}

Other methods like System.currentTimeMillis() should be avoided, because they rely on the computer date/time.
