本程序运用java语言模拟线程间的调度,在原随机调度的基础上实现轮转调度,优先级调度，处理各线程间的调度关系，并试着用信号量实现线程的锁定和释放。-This program threads using java language simulation scheduling, dispatching the former on the basis of random rotation scheduling, priority scheduling, process scheduling of th

该代码实现了在java环境先随机产生信号并绘图的解决方法-This faunction provides a solution that creats a random singal,and plot its wave
