Java多线程____线程状态Sleep()方法

Sleep():在指定的毫秒数内让当前正在执行的线程休眠

调用sleep方法时使当前的线程进入休眠状态(阻塞状态)设定休眠xxxx毫秒数后进入运行状态

同步块中的Sleep方法调用 不会释放对象锁但调用wait()方法会释放对象的同步锁

package com.test.thread;

public class TestRunnable implements Runnable {
	@Override
	public synchronized void run() {
		for (int i = 0; i < 6; i++) {
			if (i % 2 == 0) {
				try {
					System.out.println(Thread.currentThread().getName());
					Thread.sleep(2000);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			}
		}
	}

}

package com.test.thread;


public class TestMain {
	
	public static void main(String[] args) {
		
		TestRunnable runnable_01=new TestRunnable();
		Thread thread1=new Thread(runnable_01, "runnable_01");

			thread1.start();
					
	}
