philosopher(1.6)
哲学家进餐问题——Java语言实现
哲学家进餐问题是一个多线程运用的经典例子,涉及到线程同步/互斥,临界区访问问题以及一个避免死锁的解决方法。
有五个哲学家绕着圆桌坐,每个哲学家面前有一盘面,两人之间有一支筷子,这样每个哲学家左右各有一支筷子。
哲学家有2个状态,思考或者拿起筷子吃饭。如果哲学家拿到一只筷子,不能吃饭,直到拿到2只才能吃饭,并且一次只能拿起身边的一支筷子。一旦拿起便不会放下筷子直到把饭吃完,此时才把这双筷子放回原处。
如果,很不幸地,每个哲学家拿起他或她左边的筷子,那么就没有人可以吃到饭了。这就会造成死锁了。。这是需要坚决杜绝的,正如操作系统的死锁问题。()
