如何在Java中区分RUNNING状态与java.lang.Thread.State.RUNNABLE

当线程是RUNNABLE时,它可以正在运行,也可以不运行.有没有办法将其与java.lang.Thread.State#RUNNABLE区别开？

Java doc中线程的所有状态：

java.lang public class Thread.State

extends Enum

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.

A thread can be in only one state at a given point in time. These states are virtual machine states which do not reflect any operating system thread states.

package bj.thread;

public class ThreadApp2 {

    public static void main(String[] args) {
        System.out.println(Thread.currentThread().getState());
    }
}

输出：

RUNNABLE
