基本概念

什么是线程安全问题

当多个线程同时共享 一个全局变量做的操作时候,可能会收到其他线程的干扰,就会产生线程安全问题,导致数据脏读。

模拟有线程安全问题的代码

public class TicketThread implements Runnable {
    private int count = 100;

    @Override
    public void run() {
        while (count > 0) {
            try {
                Thread.sleep(30);
            } catch (Exception e) {
            }
            ticket();
        }
    }

    private void ticket() {
        if (count > 0) {
            System.out.println(Thread.currentThread().getName() + ",正在开始出售:" + (100 - count + 1));
            count--;
        }
    }

    public static void main(String[] args) {
        TicketThread ticketThread = new TicketThread();
        Thread thread1 = new Thread(ticketThread, "窗口1");
        Thread thread2 = new Thread(ticketThread, "窗口2");
        thread1.start();
        thread2.start();
    }
}
