- Java Programming Define a class CollectionBooks. This class has a data member list of type Book using the ArrayList collection. Define method add. This method add the any object to list. Define printAll. This method display all the added object in the list. Define printAll. This method display all the added object in the list. · Define int count. This method returns the number of objects added in the list. Define Book search(Object e). This method returns the object being search if not found return null. Define void remove(int index). This method remove the object in a list Add a main method with the following menu:1 – Add 2 – Count 3 – Print4 – Search 5 – Delete 6 - ExitCollection: List, Set and Map. Collection operations on primitives and custom object (Eg: For custom object Student having properties ID and Name) List , Set , Mapcode: public class PasswordGeneratorAndStorage {/*** Adds an application to the applications ArrayList. If index is -1, add application* to the end of applications. Else is index is within the size of applications, add* application at that index in applications. Otherwise, return.

- Java Objects and Linked Data: Select all of the following statements that are true. The Java Class Library's class ArrayList implements the LinkedList interface. In Java, when one reference variable is assigned to another reference variable, both references then refer to the same object. In Java, the "equals"-method that any object inherits can be overwritten to compare objects field by field.X1222: Double Ended Queue: Deque A double ended queue, known as deque, is a queue data structure that allows adding and removing elements from both ends of the queue. Instead of enqueue and dequeue, it has insert, delete, and get for both front and last of the queue as shown below. The data stored internally is stored in a ListNodesPlus object. The basic class definition is shown below: public class Deque { private ListNodePlus elements; // code ommitted for space public void clear() {...}; public int numElements () {...}; public boolean isEmpty() {...}; ● // Implement the following four methods public void insertFront (E it) { } public E deleteFront () { } public void insertLast (E it) { } public E deleteLast() { } Write the following four methods: • insertFront (E it) takes it and adds it to the front of the queue. stored internally in elements. The front of the queue is defined as position 0 in the queue. ● deleteFront () removes the element at the front of the queue and returns it.…What is the Collections class (not Collection)? A It is a class that includes several different types of collections. B It is an interface defining the methods that any collection must implement. C It provides a number of common methods that work with different collections. D It is an abstract class providing some of the methods that all collections use, and defining others that must be implemented in any collection.
- 7a. State a collection class or interface that allows the following operations to be performed. randomly access to its element iterating a collection both forward and backward directions1. Goals and Overview The goal of this assignment is to practice creating a hash table. This assignment also has an alternative, described in Section 5. A hash table stores values into a table (meaning an array) at a position determined by a hash function. 2. Hash Function and Values Every Java object has a method int hashCode() which returns an int suitable for use in a hash table. Most classes use the hashCode method they inherit from object, but classes such as string define their own hashCode method, overriding the one in object. For this assignments, your hash table stores values of type public class HashKeyValue { K key; V value; } 3. Hash Table using Chained Hashing Create a hash table class (called HashTable211.java) satisfying the following interface: public interface HashInterface { void add(K key, V value); // always succeeds as long as there is enough memory V find (K key); // returns null if there is no such key } Internally, your hash table is defined as a private…

Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class.
