Complete the method loadBuses(String bfile) that reads information bus information from a file (bfile contains the filename) . Each row in the file should trigger the creation of an instance of bus or an appropriate subclass, according to the data in table 1. All buses created should be added to an arraylist. LoadBuses should return the populated arraylist. public ArrayList loadBuses(String bfile ) { Scanner bscan = null; ArrayList blist = new ArrayList(); return blist; }

In java A supermarket wants to reward its best customer of each day, showing the customer’s name on a screen in the supermarket. For that purpose, the store keeps an ArrayList.Create a class customer having id, name, gender, and bill provide appropriate getters/setters and constructors also provide toString method.In the Store class, make an ArrayList of customers, store name, and address implement methods public void addSale(Customer c) that will add customers to the arraylist.public void RemoveCustomer(int id);public void UpdateCustomerRecord(int Id);public displayAll();public String nameOfBestCustomer() to record the sale and return the name of the customer with the largest sale. public ArrayList nameOfBestCustomers(int topN) so that it displays the top customers, that is, the topN customers with the largest sales, where topN is a value that the user of the program supplies.

Java 1. Implement ArrayUnorderedList<T> class which will extend ArrayList<T> by defining the following additional methods(i) public void addToFront(T element); //Adds the specified element to the front of the list.(ii) public void addToRear(T element); //Adds the specified element to the rear of the list.(iii) public void addAfter(T element, T target); //Adds the specified element after the specified target element.a. Create an object of ArrayUnorderedList<T> class and perform some add, remove, and search operations and finally print the entire Stack.

The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.

The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters. public static String[] split(String s, String regex) For example, split("ab#12#453", "#") returns ab, #, 12, #, and 453 in an array of String and split("a?b?gf#e", "[?#]") returns a, ?, b, ?, gf, #, and e in an array of String.
TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…
Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in ArrayList class (ArrayListLibrary arrayListLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and ArrayListLibrary insertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each insertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D. Salinger the output is: Number of linked list operations: 1 Number of ArrayList operations: 1 import java.util.Scanner;import java.io.FileInputStream;import java.io.IOException; public class Library { public static void fillLibraries(LinkedListLibrary linkedListLibrary, ArrayListLibrary arrayListLibrary) throws…
