All types of Java applications typically need to plan for recurring tasks. Enterprise applications need to schedule daily logs or nightly batch processes. A J2SE or J2ME calendar application needs to schedule the alarm time according to the user's agreement. However, the standard scheduling class Timer and timertask do not have enough flexibility to support the type of scheduled tasks that are typically req

asynchronous thread is initiated, the newly initiated asynchronous thread does not affect the previously initiated thread, and all the originating threads continue to execute, as in the following example, until all threads of the user close the program end running. ）；The state can be null or a reference to the object to pass in each time the asynchronous thread is invoked;Callback is a method that passes a parameter of type object, the return value is a delegate type of void, and is customized

The requirement is to query for a period of time, some of the schedule is repeated each year (month, day), how to get the schedule within a find?
The repetition means that the addition of the May 1 schedule of this year, I query next April-May schedule, still can find his
I hope I can give you a clue

Scheduled Tasks, recurring task settings in LinuxScheduled Task : The execution of a specific task at a specific time in the future. Of course, if the same task needs to execute twice, three or more times at different points in time, it can be treated as multiple times.Recurring Task : Refers to a task that requires periodic execution. Periodicity can be in points, hours, Tian Deng units, but not limited to these units.Commands that are commonly used
