Worker Thread in Java

Question

I need to read the data from a table every minute through thread & then perform certain action.

Should I just start a thread & put it in sleep mode for 1 minute

Answer 1

An alternative to create a thread yourself is to use the ExcecutorService, where Executors.newScheduledThreadPool( 1 ) creates a thred pool of size 1 and scheduleAtFixedRate has the signature: scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit);

public class ScheduledDBPoll
{
  public static void main( String[] args )
  {
    ScheduledExecutorService scheduler = Executors.newScheduledThreadPool( 1 );
    ScheduledFuture sf = scheduler.scheduleAtFixedRate(
        new Runnable() {
          public void run() {
            pollDB();
          }
        },
        1,  60,TimeUnit.SECONDS );
  }
}
