线程状态代码演示

package 线程停止;
//检测线程状态
public class TestState{
    public static void main(String[] args) throws InterruptedException {
        Thread thread = new Thread(() -> {//启动线程只有一个语句用lambdal表达式
            for (int i = 0; i < 5; i++) {//WAIT线程阻塞
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            System.out.println("/////////////////");
        });


        //观察状态
        Thread.State state =thread.getState();
        System.out.println(state);//NEW
        //启动后
        thread.start();//启动状态
        state=thread.getState();//更新状态
        System.out.println(state);//RUN
        while (state!=Thread.State.TERMINATED){//TERMINATED线程终止死亡
            Thread.sleep(100);
            state=thread.getState();//更新状态
            System.out.println(state);//输出状态
        }
//        thread.start();//死亡线程不能调用

    }
