线程的生命周期

线程状态的转换

通过代码输出线程的状态，代码如下

public class ThreadState_ {
    
    
    public static void main(String[] args) {
    
    
        T t = new T();
        System.out.println(t.getName() + " 状态 " + t.getState());
        t.start();
        while (Thread.State.TERMINATED != t.getState()) {
    
     //当t线程的状态，不等于终止状态
            System.out.println(t.getName() + " 状态 " + t.getState());
            try {
    
    
                Thread.sleep(500);
            } catch (InterruptedException e) {
    
    
                e.printStackTrace();
            }
        }
        System.out.println(t.getName() + " 状态 " + t.getState());
    }
}

class T extends Thread {
    
    
    @Override
    public void run() {
    
    
        while (true) {
    
    
            for (int i = 0; i < 10; i++) {
    
    
                System.out.println("hi" + i);
                try {
    
    
                    Thread.sleep(1000); //休眠1秒钟
                } catch (InterruptedException e) {
    
    
                    e.printStackTrace();
                }
            }
            break;
        }
    }
}

输出状态如下
