Java 线程在开始运行之前的状态不是新的，它是可运行的，不是吗

从基础学习开始，我对Java中的线程一无所知，我知道当创建线程时，它处于新状态。当线程处于此状态时，该线程尚未开始运行

public class MainClassForThread {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Thread t1 = new ExtendingThreadClass();
        Thread t2 = new ExtendingThreadClass();
        Thread t3 = new ExtendingThreadClass();

        System.out.println("Before start of thread the state of thread is " + t1.currentThread().getState());
        t1.start();
        t2.start();
        t3.start();
    }

}

package Threads;

public class ExtendingThreadClass extends Thread {

    public void run() {

        System.out.println("Thread running : " + Thread.currentThread().getId());
        for (int i = 0; i < 100; i++) {
            System.out.println("Thread " + Thread.currentThread().getName() + " is running for value of i " + i);
            System.out.println("State " + Thread.currentThread().getState());
        }
    }

}

问题在于这一行：

System.out.println("Before start of thread the state of thread is " + t1.currentThread().getState());

您获得当前线程，并且当前线程正在运行

您可能不想获取当前线程的状态，所以将该行更改为

System.out.println("Before start of thread the state of thread is " + t1.getState());

您将获得当前线程的状态，该线程正在运行。显然。如果您阅读文档，即的javadoc，它说返回对当前正在执行的线程对象的引用，那么当方法被显式地记录为返回对正在执行的线程的引用时，为什么您会对线程正在运行感到困惑呢，请注意警告，不要从实例调用静态方法。@shmosel您假设OP使用IDE甚至可以看到警告。

System.out.println("Before start of thread the state of thread is " + t1.getState());
