抢先优先级调度 Java中的抢占式优先级调度（OS）算法 介绍 优先级调度是一种基于优先级调度进程的方法。 在此算法中，调度程序根据优先级选择要工作的任务。 具有较高优先级的过程应首先执行。 在“抢先式优先级调度”中，当某个进程到达就绪队列时，将其优先级与就绪队列中存在的其他进程的优先级以及当时CPU正在执行的优先级进行比较时间。 接下来，将在所有可用进程中将优先级最高的那个分配给CPU。 抢占优先级调度和非抢占优先级调度之间的区别在于，在抢占优先级调度中，可以在更高优先级的作业到达时停止正在执行的作业。 一旦所有作业在就绪队列中可用，该算法将充当非抢先优先级调度，这意味着调度的作业将一

哲学家进餐 一，课程设计目的 掌握基本的同步与互斥算法，掌握进展并发执行的原理，及其所引起的同步，互斥问题的方法。 二，课程设计内容 自己编写的信号量和wait，signal操作的模拟程序，然后用其解决不死锁的哲学家问题或读者-写者问题。 三，要求及提示 本译文必须单人完成。 解决不死锁的哲学家问题，要求把哲学家们的活动过程用文字或图形可视化形式表示出来。 提示：首先设置一个“ PCB”插入或串联，其中一个分段表示“分开原因兼并标志”，本实验中，该数组有5个元素表示5个哲学家即可。它们随机提出申请以及进行“思考” ”和“吃”的行为。再设一个“筷子”数组。还需要设置一些数据结构以及需要某些分段自己考虑。 运行截图 发生死锁 不会发生死锁
