Java定义线程A、B并交替输出

需求说明
– 定义一个线程A，输出1 ～ 10之间的整数，定义一个线程B，逆
序输出1 ～ 10之间的整数，要求线程A和线程B交替输出
• 分析
– 使用sleep()方法阻塞当前线程

public class ThreadWork4 implements Runnable{
    @Override
    public void run() {
        for (int i = 1; i <= 10; i++) {
            System.out.println("A----" + i);
            try {
                Thread.sleep(1009);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] args){
        ThreadWork4 d1 = new ThreadWork4();
        Thread thread = new Thread(d1,"A");
        thread.start();

        for (int i = 10; i >=1 ; i--) {
            System.out.println("B----" + i);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
