Hash set and hash map are data structures used to store key-value pairs for efficient retrieval.
Hash set stores unique values without any specific order.
Hash map stores key-value pairs and allows fast retrieval of values based on keys.
Both use hashing to map keys to their corresponding values.
In Java, HashSet and HashMap are implementations of these data structures.
