哲学家就餐问题是一个经典的同步问题,模拟多个哲学家围坐在一张圆桌前就餐,每个哲学家需要先拿到自己右手边的筷子和左边的筷子才能开始吃饭。但是只有五根筷子可供使用,每次只有一个哲学家能够拿起一根筷子进行就餐。
以下是一个运行结果的示例:
```
Philosopher 0 is thinking
Philosopher 1 is thinking
Philosopher 2 is thinking
Philosopher 3 is thinking
Philosopher 4 is thinking
Philosopher 1 is hungry and trying to pick up left chopstick
Philosopher 1 picked up left chopstick
Philosopher 1 is hungry and trying to pick up right chopstick
Philosopher 2 is hungry and trying to pick up left chopstick
Philosopher 0 is hungry and trying to pick up left chopstick
Philosopher 3 is hungry and trying to pick up left chopstick
Philosopher 4 is hungry and trying to pick up left chopstick
Philosopher 1 picked up right chopstick and is eating
Philosopher 1 put down right chopstick and left chopstick and is thinking
Philosopher 2 picked up left chopstick
Philosopher 2 is hungry and trying to pick up right chopstick
Philosopher 2 picked up right chopstick and is eating
Philosopher 2 put down right chopstick and left chopstick and is thinking
Philosopher 0 picked up left chopstick
Philosopher 0 is hungry and trying to pick up right chopstick
Philosopher 0 picked up right chopstick and is eating
Philosopher 0 put down right chopstick and left chopstick and is thinking
Philosopher 3 picked up left chopstick
Philosopher 3 is hungry and trying to pick up right chopstick
Philosopher 4 picked up left chopstick
Philosopher 4 is hungry and trying to pick up right chopstick
Philosopher 3 picked up right chopstick and is eating
Philosopher 3 put down right chopstick and left chopstick and is thinking
Philosopher 4 picked up right chopstick and is eating
Philosopher 4 put down right chopstick and left chopstick and is thinking
```
可以看到,每个哲学家在开始时都处于思考状态,然后有些哲学家会先尝试拿起左手边的筷子,有些则是右手边的。如果成功拿起了两根筷子,就可以开始用餐,用餐结束后需要将筷子放回桌面上,然后重新进入思考状态。这个过程会不断重复,直到程序结束。
