- betterAddProduct Write a method in your Warehouse class to further optimize addProduct. As of now, it’s possible that an item is removed from a full sector to make room for a new product, even if there are other sectors which are not full. If the current sector is not full, add the product as normal. Otherwise perform a linear probing-like operation to try to find a non-full sector (if the current one is full). Keep incrementing the sector until you either find one with space, or you return to your original sector. If you get to Sector 9, wrap around to Sector 0. If you found a new sector with space, add the product into this sector. In a real-world scenario we would have to make sure to change the ID in our system and make sure it doesn’t conflict with an existing one. In this assignment that is not necessary since the output only contains the name. If you returned to the original sector, perform eviction and add the product as normal.Implement solutions for the following methods: • getCourseSize() – returns the number of students registered in the course (not in the waitlist). It should maintain the public size variable that keeps track of the number of students registered. • getRegisteredIDs() – returns an array of int[], namely registered student id’s. The length of the array is the size (number of students) in the course. • getRegisteredStudents() – returns an array of type Student[], namely the registered Students. The length of the array is the current size (number of students) of the course. • getWaitlistedIDs() – returns an array of type int[], namely the ids of students in the waitlist. • getWaitlistedStudents() – returns an array of Students in the waitlist. public class Course { public String code; public int capacity; public SLinkedList<Student>[] studentTable; public int size; public SLinkedList<Student> waitlist; public Course(String code) {…Write the Java implementation of an instance method, called countRange, inside the IntArrayBag class such that the method takes two input integer parameters, called start and end. The method then counts and returns how many elements in the bag fall in the range between start and end inclusive. For example, if start is 5 and end is 8, then the method counts how many elements in the bag are equal to 5,6,7, or 8. The method returns zero if start > end. Make sure to include the method header.
- Design and implement an insertSorted() method for the MyArrayList class. The method should receive a single object and insert it in its correct position. You can assume that the calling array is already in a sorted order. The calling array is therefore updated. Follow the three step method for designing the method. Develop the java code for the method. Create a test program to test the method thoroughly using the Integer wrapper class.Add a constructor to SeparateChainingHashST that gives the client the abilityto specify the average number of probes to be tolerated for searches. Use array resizingto keep the average list size less than the specified value, and use the technique describedon page 478 to ensure that the modulus for hash() is primeShow what the array of the HashMap would look like after all the items below have been added, assuming the HashMap class uses linear probing to resolve collisions. Assume the array is resized when the current item to be added will make the total number of items greater than or equal to the threshold value. Note that for both questions, you do not need to compute the hashcodes, since I have provided them for you. Therefore, you only need to carry out Step 2, which is translating the hashcodes to valid array indexes. Assume remainder division is used to accomplish this. The challenge of this assignment is to correctly handle all collisions that may result when translating the larger range of hascode values into the smaller range of valid array indexes. For this assignment you will not need to resize the array or re-hash items.
- You might have heard about the "Guess the Word Game", so in this game the user has to guess the letter(s) of the word one by one. There are n chances given to guess its letters where n is the number of letters in that word. You have to implement given scenario with the help of “Doubly Linked List”. Create two linkedlist, first linkedlist will be containing of complete word e.g. ELEPHANT and second linkedlist will be containing of word but having some blank letters e.g. _LEP_AN_. You have to ask user for input for every letter and insert into second linkedlist as follows: Step 1: Letter 1: Insert into second linkedlist on first place and compare 1st value of first and second linkedlist if same then go to step 2 else go to step 1 Step 2: Letter 2: Insert into second linkedlist on fifth place and compare 5th value of first and second linkedlist if same then go to step 3 else go to step 2 Step 3: Letter 3: Insert into second linkedlist on last place and compare last value of…In JAVA, use a HashMap to count and store the frequency counts for all the words from a large text document. Then, display the contents of this HashMap with given words and their frequency in the document. Next, please create a set view of the Map and store the contents in an array. Sort this array based on key value and display it. Finally, sort the array in decreasing order by frequency and display it.JAVA Create a new class HashSetManipulation with a main method. Create a new HashSet set and populate it with initial values "A", "B", and "C" using the add method. Print the size of the set using set.size(). Use a for loop to print the values in the set. Use the add method to add a new value "D" to the set and print the result of the set to show that the value has been added. Use the remove method to remove value "A" from the set and print the result of the set to show that the value has been removed. Use the contains method to check if the value "C" exists in the set and print the result.
- Import the HashMap and Map classes from the java.util package. Within the main method, a sentence is declared as a string variable and assigned the value "This is a test sentence with no repeating words". Split the sentence into words using the split method and store the result in a String array called "words". Create a new Map called "wordFrequency" that stores each word as a key and the frequency of the word in the sentence as the corresponding value using the HashMap implementation. Use a for loop to iterate through each word in the "words" array. Within the for loop, the code should use the containsKey method to check if the word is already in the Map. If the word is already in the Map, its frequency should be incremented by 1. Use the put method to add the word as the key and the incremented frequency as the value to increment it. If the word is not in the map, add it as a new key with a frequency of 1 as its value. Outside of the for loop, use System.out.println to…The number of nodes that make up the strongest linkedlist is unknown. Is there a specific one that stands out as being really long?Sorting objects in the real world https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html There are 5000 people living in the town. Every day they have new COVID-19 cases. When people show symptom, they go to the hospital and put themselves in the waiting list for testing. A new person is added at the end of the list. Due to the lack of testing kit, all in the list cannot be tested. Hospital has to sort them and select a few. Since the elderly is very weak to the COVID-19, every midnight the doctors sort the people in the list by their age to decide who is taking the test for the next day depending on the availability of testing kit. Input to the program has the form where the first line indicates how many days they will do the operation. For each day, the input starts with the day number, along with the following patient list where each element represents the name of patients and the age. The input ends with the number of available testing kits. The output display, at…
