从java.lang.Thread.State可以看到java线程有以下状态：

• 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.

These states are virtual machine states which do not reflect any operating system thread states.

操作系统定义的线程状态有：

新建，就绪，阻塞，运行，死亡。

java线程状态BLOCKED，WAITING，TIMED——WAITING对应操作系统线程的阻塞状态。
