Java中的线程让步Thread.yield()

class MyThead implements Runnable
{
	public void run()
	{
		for (int i = 1; i <= 100; i++)
		{
			System.out.println("thread======>" + Thread.currentThread().getName());
			if (i >= 90)
			{
				Thread.yield();
				System.out.println(i + "     让路 给thread======>" + Thread.currentThread().getName());
			}
		}
	}
}

public class TheadMain
{
	public static void main(String[] args)
	{
		MyThead myThead = new MyThead();
		Thread thread1 = new Thread(myThead, "AAA");
		Thread thread2 = new Thread(myThead, "BBB");
		thread1.start();
		thread2.start();
	}
}
