When these two methods fail to align, collections lose their reliability, leading to poor performance or issues like duplicate entries caused by hash collections.
The best solution is never to override the hash and equals and rely on object identity.
A mismatch or poor implementation can lead to unpredictable bugs, highlighting the importance of carefully testing the behavior of equals() and hashCode().
Using effective hashes and avoiding mutable keys are essential strategies for maintaining the integrity of hashed collections.
