Thread-线程状态

线程状态

Thread.State

• NEW 线程尚未开始
• RUNNABLE jvm正在执行
• BLOCKED 线程阻塞中
• WAITING 无限期的等待另一个线程执行
• TIMED_WAITING 线程正在等待另一个线程上执行一个动作指定的等待时间
• TERMINATED 线程已退出

import java.lang.Thread.State;

public class ThreadState {

	public static void main(String[] args) {
		Thread t = new Thread(()->{
			for(int i=0;i<20;i++) {
				try {
					Thread.sleep(10);
				}catch(InterruptedException e) {
					e.printStackTrace();
				}
				Thread h = new Thread(new MyThread());
				if(i==15) {
					h.start();
					try {
						h.join();
					} catch (InterruptedException e) {
						e.printStackTrace();
					}
				}
				System.out.println("Running---->"+i);
			}
		});
		
		State s = t.getState(); //NEW
		System.out.println(s);
		
		t.start();
		s = t.getState(); //RUNNABLE
		System.out.println(s);
		
		while(true) {
			try {
				Thread.sleep(10);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			s = t.getState();//出现WAITING和WIMED_WAITING
			if(State.TERMINATED==s)break;
			System.out.println(s);
		}
		
		s = t.getState();//线程退出 TERMINATED
		System.out.println(s);
		
		
	}
}
