Java線程 Block和Waiting的異同

可以參考文章

http://stackoverflow.com/questions/2534147/java-thread-wait-blocked

我的理解

1 相同點

線程都不是運行狀態

2 不同點

waiting是在資源的等待隊列中，等待被notify，notify後將會到Runable狀態，

但是要想運行還得過monitor這關。

參考

In other words, both BLOCKED and WAITING are status of inactive threads, but a WAITING thread cannot be RUNNABLE without going to BLOCKED first. WAITING threads "don't want" to become active, whereas BLOCKED threads "want" to, but can't, because it isn't their turn.
