Java 死锁demo

线程：a，b
资源：1，2
简单说就是线程a持有资源1需要资源2，线程b持有资源2需要资源1，产生死锁。

public class DeadLock {
    public static void main(String[] args) {
        ReentrantLock alock = new ReentrantLock();
        ReentrantLock block = new ReentrantLock();

        new Thread(()->{
            alock.lock();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            block.lock();
            block.unlock();


            alock.lock();
        }).start();

        new Thread(()->{
            block.lock();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            alock.lock();
            alock.unlock();


            block.lock();
        }).start();
    }
}
