Java: object.hashCode() and Objects.hashCode(object)

Question

A simple, short question: does object.hashCode() and Objects.hashCode(object) equal? What is the difference? Do they count the same hash from the objects?

Answer 1

As you can see in implementation of it

public static int hashCode(Object o) {
    return o != null ? o.hashCode() : 0;
}

yes. It prevents from NPE if object o is null.

Answer 2

Objects.hashCode(object) will return zero if object is null.

Whereas a NullPointerException would be thrown for object.hashCode() in that case.

For a non-null reference, the functions are equivalent.
