说明：  用java语言编写的带有界面的模拟操作系统进程调度的程序，可随机生成10个进程，采用三种算法执行，即——1-先进先出调度算法 2-基于优先数的调度算法 3-最短执行时间调度算法
(Java language interface with the operating system process scheduling simulation program, can be randomly generated 10 process, the implementation of the three algorithms, namely- 1- FIFO scheduling algorithm- scheduling algorithm based on priority number 3-shortest execution time scheduling algorithm)
