in a java method
In this project, you are asked to use Hash Table to store Product information for a Store. The program allows you to supplement the Store with additional new Products. The Product information includes the following: String supplierAddress // in this form: area_block_street_building phone int id 1/product id consists of 4 digits String product Name double price You need to write and submit a java program that includes three classes: Product.java, Store.java and Test.java. 1) Class Product Instance variables: private String supplier Address: private int id; private String productName; private double price; Methods: A constructor that initializes the instance variables. Set and get methods for each instance variable. toString method that returns a string containing supplierAddress, id, product Name and price. 2) Class Store Instance variables: private Product table(); // Hash table private int size: // Hash table size Methods: public Store(int size) Create an array of Products and save the size of the hash table. public int hashFun(String supplier Address, int id) Split the supplier Address string, based on underscore. Then, find the hash value according to the following steps: 1. Take the first character of the area, block, street, building and phone 2. Convert them to ASCII. 3. Cast them into int. 4. Add each value with power of 3 (3^0,3-1,3-2, 343) accordingly. 5. Add the result to the product id. 6. Finally return (result) % table size to get the hash value. public boolean insert(Product p) Insert the product p in the proper location and return true. When a collision happens, use quadratic propping. If the hash table is full, return false. Note: duplication is not allowed. public void printTable() Call toString() method and print the contents of the Hash Table in a readable way. public int suppliers Count and return number of suppliers that deal with the store. public void maxPrices() print the product with the maximum price for each supplier. public boolean deletProduct(String supplierAddress, int id) Search the hash function and delete product the has the given attributes (supplierAddress, id). 3) Class Test In the main method, create an object of class Store with size 11. Display a menu of choices, as shown in the sample output. Add your sample output as a comment at the end of the test class. Sample output: 1. Insert product 2. delete product 3. Print all products 4. Count the number of suppliers. 5. Print product with max price per each supplier 6. Exit
