Program Plan Intro

Animation of linear probing

Program plan:

  • Import the required package.
  • Create the class “Ex27_06”.
  • In the main() function,
    • Create the buttons to perform insert, delete and search operations.
    • Create the vertical and horizontal box to add the entries.
    • Make the alignment of the pane.
    • Set the title and scene for the animation.
    • For each button raise the event through ActionListener interface.
    • Create the class Hashview,
      • Set the table size to set the hash values.
    • Create a class MyHashMap,
      • Define the constructor MyHashMap() to construct the map with the specified initial capacity and load factor.
      • Define the method clear() to remove the entries from map.
      • Define the method containsKey() to check and return the Boolean value True if the specified key is in the map.
      • Define the method containsValue() to return true if specific value is found.
      • Define the method isEmpty() to return true if the map contains no entries.
      • Define the method put() to add the entry into map.
      • Define the method remove() to remove the entries from map.
      • Define the method rehash() to rehash the map values.
    • Declare the static interface.
      • Declare the method clear() to clear the entries of the map.
      • Declare the method containsKey() and it returns true if the value is present in the amp.
      • Declare the method containsValue() to return true if specific value is found.
      • Define the method get() to return the first value of the map.
      • Define the method put() to put the entries in the map.
      • Define the method size() to return the number of mappings in the map.
      • Define the method Entry() to enter the value of element.
      • Define the method getKey() to return the value.
      • Define the method toString() to represent the string value of key.

- 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 otherwise.(vi)…
2) Hash Innards Homework • Unanswered Select all true statements from the below. Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V a A hash function takes a key and produces an index into the hash table. The next step in this process is often something like 'h%SIZE' so that the hash value of the key will fit within the table b (having SIZE elements, you see). Common techniques involve exclusive or of bits within the key and folding different sections of bits within the key into each other. The best hash method for character strings is to simply add up the ASCIlI values of their individual characters. Coming up with a perfect hash for a given set of keys can be a difficult and time-consuming task.
I need help urgently to be able to understand how to do this program it is written in C++ but I am currently lost as to how I should start or do it or what is it even asking I would highly appreciate any good help
