OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Write an abstract data type for a queue whose elements include both a 20-character string and an integer priority. This queue must have the following methods: enqueue, which takes a string and an integer as parameters; dequeue, which returns the string from the queue that has the highest priority; and empty. The queue is not to be maintained in priority order of its elements, so the dequeue operation must always search the whole queue.C++ A queue is essentially a waiting list. It’s a sequence of elements with a front and a back. Elements can only be added to the back of the queue and they can only be removed from the front of the queue. Elements are kept in order so that the first element to enter the queue is the first one to leave it.Write an abstract data type for queues whose elements store 10-characternames. The queue elements must be dynamically allocated from theheap. Queue operations are enqueue, dequeue, and empty. Use eitherC++, Java, C#, or Ruby
- 15. Implementing Queue as a Classplease convert this into c++ import java.util.Iterator;import java.util.NoSuchElementException; public class Queue<Item> implements Iterable<Item> { private int n; // number of elements on queue private Node first; // beginning of queue private Node last; // end of queue // helper linked list class private class Node { private Item item; private Node next; } /** * Initializes an empty queue. */ public Queue() { first = null; last = null; n = 0; } /** * Returns true if this queue is empty. * * @return {@code true} if this queue is empty; {@code false} otherwise */ public boolean isEmpty() { return first == null; } /** * Returns the number of items in this queue. * * @return the number of items in this queue */ public int size() { return n; } /** * Returns the number of items in this queue. * * @return the…java: Implement the class Node public class Node { private char data; private Node nextNode; //implements default constructor //implements parameterize constructor take integer as input in parameter a assign that integer to data and assign null to nextNode //implement setters and getters } Implement the class Stack having one member having type Node public class Stack { private Node top; public void push (); public Node pop (); public Boolean isEmpty(); return true if stack is empty // implements all its function and write time complexity of its function
- ALL TRUE OR FALSE QUESTIONS 1. A "deque" allows an application to enqueue and dequeue from both front and rear of a queue. 2. The Queue ADT of the text is defined to hold elements of type Objec 3. Java supports inheritance of interfaces. 4. The text's array-based queue implementations use the fixed-front approach. 5. If N represents the number of elements in the queue, then the dequeue method of the ArrayBoundedQueue class is O(1). 6. When an object of class LinkedQueue represents an empty queue, its rear variable is 0. 7. A standard linked list provides a good implementation of a "Deque". 8. When implementing a queue with a linked list, the front of the queue is also the front of the linked list. 9. Our LinkedQueue class implements the QueueInterface interface. 10. The text's array-based queue implementations use the floating-front approach.StackQueuePostfix A. Pointer_based queuea. Define the class PoiQueue with no implementation; i.e. declare the datamembers, and the function members only (Enqueue, Dequeue, IsEmpty,GetHead etc.).b. Implement the Enqueue method of the above classB. Array_based non-circular queue:a. Define the class Queue using one dimensional array representation with noimplementation; i.e. declare the data members, and the function membersonly (Enqueue, Dequeue, IsEmpty, GetHead etc.).b. Implement the Denqueue method of the above classLanguage: C++ Note: Write both parts separately. Part a: Complete the above Priority Queue class. Write a driver to test it. Part b: Modify the above class to handle ‘N’ different priority levels
- If class Queue is implemented using a linked list. a) Mention the data members of the class b) Build the copy constructor of class QueueWithout using C++ queue STL, write a simple menu based selection to insert, delete, show and exit from queue. 1. Create a class called Queue with member variable queueArr as integer queue array, integer rear and integer front to keep track both rear and front element in the queue array. 2. Define several member functions in Queue such as a a. constructor – initialize both rear and front to -1 b. insert – receive an integer and check if queue is full, if not then insert the integer to the queue array c. delete – delete front element from queue if front is not equal to rear (empty) d. display – if rear is not equal to front, then print out the queue array. 3. Write a main function to test the Queue class.1. Implement the “missing” front and rear operations in JAVA using constructor and Also write output: class Queue { private int maxSize; private long[] queArray; private int front; private int rear; private int nItems; public Queue(int s) // constructor { maxSize = s; queArray = new long[maxSize]; front = 0; rear = -1; nItems = 0; } // public void insert(long j) { // put item at rear of queue // public long remove() { // take item from front of queue //And then return } // public long peekFront() { // peek at front of queue //Return queue array front } // public boolean isEmpty(){ // true if queue is empty //return nItems zero } // public boolean isFull() { // true if queue is full return } // public int size() // number of items in queue { //return nItems; } // } // end class Queue //////////////////////////////////////////////////////////////// class QueueApp { public static void main(String[] args) { Queue theQueue = new Queue(5); // queue holds 5 items…
