# DeadLock

两个线程分别运行以下代码的eatDrink和drinkEat， 会不会发生死锁：

```java
public class DeadLock {
    private final String eat = "吃饭";
    private final String drink = "喝水";

    public void eatDrink() {
        synchronized (eat) {
            try {
                Thread.sleep(3000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            synchronized (drink) {
                // doSomething
            }
        }
    }

    public void drinkEat() {
        synchronized (drink) {
            try {
                Thread.sleep(3000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            synchronized (eat) {
                // doSomething
            }
        }
    }
}
```
