WebIn the data structure, hashing is the most important concept that is used to convert a given key into another value. The new value can be generated by using the hash function. In this section, we will understand the concept of rehashing in Java along with the load factor and hashing concept. Rehashing WebIntroduction In Hashing, we have seen that hashing takes a key as an input and returns us the memory address (index in hash-table) where the key is stored. We also have discussed about a problem i.e. i.e. collision which occurs when the hash function generates the same index for two different keys.
