当线程RUNNABLE 时，它可以运行，也可以不运行。有没有办法将它与 java.lang.Thread.State#RUNNABLE 区分开来？
Java文档中线程的所有状态:
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
最佳答案
如您所说，可运行线程实际上可能正在运行，也可能未运行。由操作系统给线程运行时间。 不过，Java 规范并未将此称为单独的状态。一个正在运行的线程仍然处于可运行状态，无法通过 java 以简单的方式区分这两种状态。
关于java - Java中如何区分RUNNING状态和java.lang.Thread.State.RUNNABLE，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55558854/
