操作系统实验(生产者消费者问题java实现)

1、操作系统实验（生产者消费者问题java实现）操作系统实验(生产者消费者问题java实现)一实验目的1深刻理解进程同步的概念。2掌握经典同步问题，生产者一一消费者问题。二实验设备PC机三实验内容在Java开发平台模拟经典进程同步问题，生产者一一消费者问题。四程序的主要代码import javaawt*;import javax swing *;import javaawt.event*;public class PAC extends JFrameprotected JButtonproducerl, producer2, producer3, consumerl, consumer2, con
