    No, java.lang.Object doesn’t extend anything. If you ask Object.class for its superclass, it will return null.

    It would be more accurate to say that every class except Object inherits directly or indirectly from Object. The wording of the Java Language Specification says:

    Each class except Object is an
    extension of (that is, a subclass of)
    a single existing class (§8.1.4) and
    may implement interfaces (§8.1.5).

    and also:

    The extends clause must not appear in
    the definition of the class Object,
    because it is the primordial class and
    has no direct superclass.
