观测线程状态

观测线程状态

package com.Luoking.Thread;

public class ThreadState {


    public static void main(String[] args) throws InterruptedException {
        //线程逻辑
        Thread thread = new Thread(()->{
            for (int i = 0; i < 5; i++) {
                try {
                    Thread.sleep(1000);//线程休眠
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            //休眠之后，打印一句话
            System.out.println("我起床了！！");
        });
        //获取新生线程状态
        Thread.State state = thread.getState();
        System.out.println(state);
        //启动线程
        thread.start();
        state = thread.getState();
        System.out.println(state);
        while(state!=Thread.State.TERMINATED){//只要线程不是死亡，就一直循环
            Thread.sleep(100);
            state = thread.getState();
            System.out.println(state);
        }
        System.out.println("啊，，我凉凉了");
    }
}
