观察线程的5个状态 线程不能重新启动

package com.Java;

//观测线程状态
public class TestState {
    public static void main(String[] args) throws InterruptedException {

        Thread thread = new Thread(() -> {
            for (int i = 0; i < 5; i++) {
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            System.out.println("线程执行完毕");
        });

        Thread.State state = thread.getState();
        System.out.println(state);  //NEW

        thread.start();
        state = thread.getState();//Runnable
        System.out.println(state);

        while (state != Thread.State.TERMINATED) {//线程不停止就一直循环
            Thread.sleep(100);
            state = thread.getState();//更新线程状态
            System.out.println(state);  //TIMED_WAITING
        }
