What properties or methods are inherited from the object in object-oriented programming?

In Java, all classes inherit from the Object class, which defines basic methods available to all objects:

• toString() — returns a string representation of the object.
• equals(Object obj) — compares objects for equality.
• hashCode() — returns the hash code of the object, used in collections.
• getClass() — returns a Class object describing the class of the object.
• clone() — creates a copy of the object (supported by the Cloneable interface).
• finalize() — called before garbage collection (deprecated method).
• wait(), notify(), notifyAll() — methods for thread work and synchronization.

All these methods are available to any object in Java unless overridden in subclasses.
