A thread state. A thread can be in one of the following states:
NEW
A thread that has not yet started is in this state.
RUNNABLE
A thread executing in the Java virtual machine is in this state.
BLOCKED
A thread that is blocked waiting for a monitor lock is in this state.
WAITING
A thread that is waiting indefinitely for another thread to perform a particular action is in this state.
TIMED_WAITING
A thread that is waiting for another thread to perform an action for up to a specified waiting time is in this state.
TERMINATED
A thread that has exited is in this state.
参考：http://docs.oracle.com/javase/6/docs/api/java/lang/Thread.State.html
对于RUNNABLE状态有点违反我的常识，既然是“A thread executing”，为什么不标记为RUNNING或者EXECUTEING？
那又为什么WAITING状态不是WAITABLE？
各位认为是出于什么考虑这样做的？

我的理解线程runnable是vm的事， 但是它running不running还得OS说了算

是否真正 Running 是可以由 VM/OS 决定的，打个比方，如果在GC阶段，需要暂停所有线程。但这个过程是透明的，所以Runnable 比 Running 意义上更加合理。

VM/OS会从若干runnable(ready)状态的线程中挑选一个运行, 所以处于ready状态的线程可能有许多, 而真正在运行线程的只有几个.
waiting的线程不在ready queue里面, 如果没有被唤醒就不会被调度到的. |

这个帖子比较有意义。
之前一直没深究这个。 |
