Answer: ABD
以下哪些调度器元素鼓励对象的重用?
Schedule objects do not specify any action to be performed; they simply generate execution dates that any job can use. Program and job arguments allow the jobs and programs to be reused by simply changing the arguments that are passed in. Job classes simplify the management of jobs, but they do not specifically encourage job reuse.
日程表对象不指定任何要执行的动作,他们简单地生成任何作业都可以使用的执行日期。
程序和作业参数允许通过简单地改变传入的参数可以重复使用的作业和程序。
作业类简化了作业的管理,但他们并不特别鼓励作业重用。
