For creating a task, you need to extends TimerTask and Timer can be used to set time for the task. TimerTask : It is task which ... The Quick, Easy, and Often Incorrect Way: System.currentTimeMillis() We start our list of ways to measure elapsed time in Java with a solution that’s easy but often incorrect. First, we’ll show a quick example of how to perform the calculation, and after that we’ll explain the code: David giuntoli familySep 15, 2019 · Java System class currentTimeMillis() method with example System class currentTimeMillis() method : Here, we are going to learn about the currentTimeMillis() method of System class with its syntax and example.
