package test;

public class 线程同步 implements Runnable {

    public static void main(String[] args) {
        线程同步 data = new 线程同步();
        Thread th1 = new Thread(data, "陈俊某");
        Thread th2 = new Thread(data, "某某飞");
        th1.start();
        th2.start();
    }

    boolean bFlag = true;

    @Override
    public void run() {
        while (true) {
            if (Thread.currentThread().getName().equals("陈俊某") && bFlag) {
                System.out.println("陈俊某");
                bFlag = false;
            } else if (Thread.currentThread().getName().equals("某某飞") && !bFlag) {
                System.out.println("某某飞");
                bFlag = true;
            }
            try {
                Thread.sleep(1000);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
