    • sleep

      public static void sleep(long millis)
      Makes the current thread to sleep for a given amount ot milliseconds.
      Parameters:
      millis - the time to sleep in milliseconds

    • printProgress

      public static void printProgress(int current, int total)
      Prints a progress bar at the command line for any general process represented by several tasks (steps). The bar is updated at the current line. If nothing is printed between updates, the bar is shown at the same place. You can use it like the sample below: 
       

 final int total = 100;
 for (int i = 0; i <= total; i++) {
     Util.sleep(120); //simulates some task (use your own code here)
     Util.printProgress(i, total);
 }
      Parameters:
      current - the index of the current finished task (step)
      total - the total number of tasks (steps)
