What happens if two different objects in the system have the same hash function value?

If two different objects have the same hash value (a so-called hash collision), this can lead to problems in data structures that use hashes for quick access, such as dictionaries or sets.

In such cases, the system should handle collisions correctly to avoid data loss and ensure proper behavior. This is usually implemented through:

• Storing multiple elements with the same hash in one "bucket" and sequentially searching through them.
• Using additional comparison methods (for example, the isEqual method in iOS) to precisely determine if objects are equal.

Thus, having the same hash does not mean the objects are equal, but only indicates a potential need for additional verification.
