线程状态

线程执行完毕后不能再次运行,不能再次start()

public class TestThreadState {
    public static void main(String[] args) {
        Thread thread  = new Thread(()->{
            for(int i = 0;i<5;i++){
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        });
        System.out.println(thread.getState());
        thread.start();
        System.out.println(thread.getState());
        while(thread.getState() != Thread.State.TERMINATED){
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println(thread.getState());
        }
        System.out.println(thread.getState());
        thread.start();
    }
}
