Hash Code: First, a hash function converts a search key to an integer value and then it compresses this hash code into an index in the hash table. The hash code is simply a 32-bit signed int number, where the object is managed by a hash table. Actually, hash code is not a unique number for an object. The two objects will return the same hash code if both the objects are equal.
