龟兔赛跑（多线程）

能更好的的理解多线程

package Demo11Thread;

import java.util.SortedMap;

/**
 * 龟兔赛跑
 */
public class Race implements Runnable{
    private static String winner;

    @Override
    public void run() {
            for (int i = 0; i <= 1000; i++) {
                //模拟兔子休息，每十步休息一次
                if (Thread.currentThread().getName().equals("兔子") && i%10 ==0) {
                    try {
                        Thread.sleep(10);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                //判断比赛是否结束
                boolean flag = Win(i);
                if (flag){
                    break;
                }
                System.out.println(Thread.currentThread().getName() + "跑了" + i + "步");
            }
    }
    public boolean Win(int steps) {

        if (winner != null) {
            return true;
        }
            {
            if(steps >= 1000){
            winner = Thread.currentThread().getName();
            System.out.println("winner is" + winner);
            return true;
            }
        }
        return false;
    }

    public static void main(String[] args) {
        Race race= new Race();

       new Thread(race,"兔子").start();
       new Thread(race,"乌龟").start();

    }
}

运行结果

兔子每10步休息一次。Thread.sleep
