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:

- 3.25 Fixed Sized Deque Your task is to create an implementation of the Java Deque interface that can only hold N items where N is a number passed into the constructor. Note that most (if not all) of the unit tests rely on the method object[] toArray() inherited from Collection. Therefore, you must make sure you implement that method correctly in order to get most of the points. 301664.1524810.gpazay7 LAB АCTIVITY 3.25.1: Fixed Sized Deque 0/ 70 Submission Instructions Compile command javac FixedsizedDeque.java -xlint:all -encoding utf-8 We will use this command to compile your code Upload your files below by dragging and dropping into the area or choosing a file on your hard drive.

- *using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…1.

- · Exercise # 2: Implement a class Portfolio. This class has two objects, checking and saving, of the type bankAccount that was developed in the worked example. Initialize the 2 bank accounts with 0 initial balance. . Implement four methods • def deposit (self, amount, account) • def withdraw (self, amount, account) • def transfer (self, amount, account) • def getBalance (self, account) • Here the account string is "S" or "c" for Saving and Checking, respectively. For the deposit or withdraw, it indicates which account is affected. For a transfer, it indicates the account from which the money is taken; the money is automatically transferred to the other account. • To test your class: . create one Potfolio object • deposit 10000 in its checking account . transfer 5000 from checking account to saving account . withdraw 2500 from checking account display the balance of both accounts • A run for the above test program will result in the following output 5000.0 Saving balance = Checking…only in java not in java c++ 1.

- Create a Vector2D class with properties x and y and a proper constructor method. Plus, minus and multiplication with a scalar operators should be overloaded. Create a Body class with properties of pos, vel, mass and constructor(float Mass, Vector2D Pos, Vector2D Vel), addForce(Vector2D F) and Move(float dt) methods. Your program should create an array or collection of Bodies, at each time step (dt), calculate forces that bodies exert each other and apply accordingly. Finally, in a 2D space, bodies should move freely based on their properties and applied forces. You can use option buttons or another element to represent bodies and move them inside the form.Java programming I have to do the "Resize method" which I believe if the array is full, it should resize so there is space.
