Examples of java.util.Timer.schedule()

java.util.Timer.schedule()
Schedules the specified task for execution after the specified delay. @param task task to be scheduled. @param delay delay in milliseconds before task is to be executed. @throws IllegalArgumentException if delay is negative, ordelay + System.currentTimeMillis() is negative. @throws IllegalStateException if task was already scheduled orcancelled, or timer was cancelled.

        int delaySecs = GlobalProperties.getInt("ebean.cacheWarmingDelay", 30);
        long sleepMillis = 1000 * delaySecs;


        if (sleepMillis > 0) {
          Timer t = new Timer("EbeanCacheWarmer", true);
          t.schedule(new CacheWarmer(server), sleepMillis);
        }
      }


      // start any services after registering with clusterManager
