Приведи пример возникновения Deadlock

public class DeadlockExample {
    static final Object lock1 = new Object();
    static final Object lock2 = new Object();

    public static void main(String[] args) {
        Thread t1 = new Thread(() -> {
            synchronized (lock1) {
                System.out.println("Thread 1: Holding lock1");
                try { Thread.sleep(100); } catch (Exception e) {}
                synchronized (lock2) {
                    System.out.println("Thread 1: Holding lock1 and lock2");
                }
            }
        });

    Thread t2 = new Thread(() -> {
        synchronized (lock2) {
            System.out.println("Thread 2: Holding lock2");
            try { Thread.sleep(100); } catch (Exception e) {}
            synchronized (lock1) {
                System.out.println("Thread 2: Holding lock2 and lock1");
            }
        }
    });

    t1.start();
    t2.start();
}

Здесь t1 захватывает lock1 и ждет lock2, а t2 захватывает lock2 и ждет lock1. Оба потока бесконечно ожидают друг друга.
