[Solved] What classes in java are overriding equals() and hashCode() methods? [closed]

Question

Taken from here

The contract between equals() and hashCode() is:
1) If two objects are equal, then they must have the same hash code.
2) If two objects have the same hash code, they may or may not be equal.

Therefore: any class that defines equals() differently than this == other must have its own implementation of hashCode()
