WebIf two pieces of data share the same value in a hash table, then it is known as a collision in hashing. As the key of hash function is a small number for a key which is either a big integer or a string, then probably the two keys result in the same value. WebHashing Techniques in Java The hash function is a key-value mapping function. When two or more keys are mapped to the same value using these hashing methods, there exists … WebNov 11, 2024 · HashMap works on the principle of hashing — an algorithm to map object data to some representative integer value. The hashing function is applied to the key object to calculate the index of the bucket in order to store and retrieve any key-value pair.
