java 多线程-yield礼让

yield 礼让线程，让当前正在执行的线程暂停而不是阻塞线程 将线程从运行状态转入就绪状态 让cpu调度器重新调度

public class n {

public static void main(String[]args)
{
	test t =new test();
	new Thread(t,"a").start();
	new Thread(t,"b").start();
	
	
}

}

class test implements Runnable{

public void run()
{
	System.out.println(Thread.currentThread().getName()+"-->start");
	Thread.yield();//礼让
	System.out.println(Thread.currentThread().getName()+"-->end");
}
}

例2：

public class n {

public static void main(String[]args)
{
	new Thread(()->
	 {
		for(int i=0;i<5;i++)
		{
			System.out.println("a"+i);
		}
	}).start();
	
	for(int i=0;i<5;i++)
	{
		if(i%2==0)
		{
			Thread.yield();
		}
		System.out.println("b"+i);
	}
}

}
