java写一个多线程死锁的代码

在 Java 中，死锁通常发生在两个或更多的线程相互等待对方释放资源的情况下。这里是一个简单的示例，展示了如何编写可能会导致死锁的多线程代码：

public class DeadLockExample {
    private final Object lockA = new Object();
    private final Object lockB = new Object();

    public void threadOne() {
        synchronized (lockA) {
            System.out.println("Thread One acquired lock A");
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            // 死锁：尝试获取无法立即获得的锁
            synchronized (lockB) {
                System.out.println("Thread One acquired lock B");
            }
        }
    }

    public void threadTwo() {
        synchronized (lockB) {
            System.out.println("Thread Two acquired lock B");
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            // 死锁：尝试获取无法立即获得的锁
            synchronized (lockA) {
                System.out.println("Thread Two acquired lock A");
            }
        }
    }

    public static void main(String[] args) {
        DeadLockExample example = new DeadLockExample();
        new Thread(example::threadOne).start();
        new Thread(example::threadTwo).start();
    }
}
