What’s the difference between fixed rate and fixed delay in Spring Scheduled annotation?

• fixedRate : makes Spring run the task on periodic intervals even if the
  last invocation may still be running.
• fixedDelay : specifically controls the next execution time when the
  last execution finishes.

In code:

@Scheduled(fixedDelay=5000)
public void updateEmployeeInventory(){
    System.out.println("employee inventory will be updated once only the last updated finished ");
    /**
     * add your scheduled job logic here
     */
}


@Scheduled(fixedRate=5000)
public void updateEmployeeInventory(){
    System.out.println("employee inventory will be updated every 5 seconds from prior updated has stared, regardless it is finished or not");
    /**
     * add your scheduled job logic here
     */
}
