Object enclosed by parentheses

I'm learning data structures and encountered the code below. I'm really curious about the meaning of parentheses around new Object();.

public class HashTable <K,V> implements Iterable<K> {
    private final K TOMBSTONE=(K) (new Object());
}

I assume the parentheses around K are for down casting that makes the new Object(); be of data type K. What are the parentheses around new Object(); for?

Could you please tell me in plain English?

The parentheses aren't functionally required. They're just there for readability. It would compile without them:

public class HashTable <K,V> implements Iterable<K> {
    private final K TOMBSTONE=(K) new Object();
}
