Process
java进程调度(优先级)进程调度算法:采用最高优先数优先的调度算法(即把处理机分配给优先数最高的进程)和先来先服务算法。每个进程有一个进程控制块( PCB)表示。进程控制块可以包含如下信息:进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。
进程的优先数及需要的运行时间可以事先人为地指定(也可以由随机数产生)。进程的到达时间为进程输入的时间。进程的运行时间以时间片为单位进行计算。每个进程的状态可以是就绪
W(Wait)、运行R(Run)、或完成F(Finish)三种状态之一。就绪进程获得
CPU后都只能运行一个时间片。用已占用CPU时间加1来表示。如果运行一个时间片后,进程的已占用
CPU时间已达到所需要的运行时间,则撤消该进程,如果运行一个时间片后进程的已占用CPU时间还未达所需要的运行时间,也就是进程还需要继续运行,此时应将进程的优先数减1(即降低一级),然后把它插入就绪队列等待CPU。每进行一次调度程序都打印一次运行进程、就绪队列、以及各个进程的
PCB,以便进行检查。 (Java process scheduling)

Homework08
说明: 利用前面提到的SupplyDepot、Transport和CapableOfBeingRefefuelled类/接口,为Air-plane增加一个main()方法,然后为supplyDepot等增加必要的字段、参数和代码,以便CapableOfBeingRefefuelled能够告诉service()方法需要加多少油。同时要确保Depot中的油应相应地减少,而实现CapableOfBeingRefefuelledi的类对象应相应地增加。(Using the upplyDepot, Transport and ApableOfBeingRefefuelled classes/interfaces mentioned above, add a main () method to Air-plane, and then add the necessary fields, parameters and codes to supplyDepot, so that CapableOfBeingRefefuelled can tell service () how much fuel the method needs. At the same time, we should ensure that the oil in Depot should be reduced accordingly, and the class objects that implement Capable OfBeingRefefuelledi should be increased accordingly.)
