Implement a dynamically resizable hash table to store book names and 10-digit ISBN numbers. Use an initial table size of 11 and a load factor of 0.70. Use the extraction method with division using the last three digits of the ISBN as the first hash address. For a collision, use linear probing. For your testing, make sure you deliberately code ISBNs so that collisions will occur, and demonstrate how the same set of values can result in different hashes, depending on the order in which they are added. Test adding items until the hash table must be resized. Test finding and removing items from the hash table.

(in java)- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table. Themethod returns true, if the insertion is successful. If an element is already inthe table, the function insert should return false.(iv) Implement search, which takes an integer and finds it in the table. The methodreturns true, if the search is successful and false otherwise.(v) Implement delete, which takes an integer and deletes it form the table. Themethod returns true, if the deletion is successful and false…

Consider the idea of implementing modular hashing for integer keys with thecode (a * k) % M , where a is an arbitrary fixed prime. Does this change mix up thebits sufficiently well that you can use nonprime M?
