Run code every second by using System.currentTimeMillis()

Question

I am trying to run a line of code every second by using System.currentTimeMillis();.

The code:

     while(true){
           long var = System.currentTim         


        

Answer 1

preferred way:

ScheduledExecutorService scheduler = Executors.newSingleThreadScheduledExecutor();

Then pass in Runnables like:

scheduler.scheduleWithFixedDelay(myRunnable, initDelay, delay, TimeUnit.MILLISECONDS);

I wouldn't use the Timer. Schedulers are built to handle problems that Timers can cause. Also, the Thread.sleep is good for a simple program that you're writing quickly for proof of concept type things but I wouldn't use it in the enterprise world.
