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:
To hide one of a class’s members, you declare the member using which of the following
keywords?
a. Hide
b. Invisible
c. Private
d. ReadOnly

- mau Open Leathing inta... - The class has data members that can hold the name of your cube, length of one of the sides and the color of your cube. - The class has a constructor that accepts the name, length of one of the sides, and color as arguments and sets the data members to those values. - The class has the following methods to set the corresponding data member. setName(string newName) setSide(double newSide) setColor(string newColor) - The class has a method called getVolume() that returns the volume of the cube, calculated by cubing the length of the side. - The class has a method called volumelncrease(double newVolume) that receive the percent the volume should increase, and then the side to the corresponding value. i - For example, 2.5 indicates 2.5% increasing of the volume. So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube…Static & Not Final Field: Accessed by every object, Changing Non-Static & Final Field: Accessed by object itself, Non-Changing Static & Final: Accessed by every object, Non-Changing Non-Static & Not Final Field: Accessed by object itself, ChangingRead the following situation and decide how the variables should be defined. You have a class named HeartsPlayerA round of Hearts starts with every player having 13 cardsPlayers then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep)Players then strategically play cards in order to have the lowest scoreAt the end of the round, points are cumulatively totaled for each player.If one player’s total is greater than 100, the game ends and the player with the lowest score wins. 1. How should the following data fields be defined (with respect to final and static)?(a) playerPosition (These have values of North, South, East, or West)(b) directionOfPassing(c) totalScore…Assignment:The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date created
- Hints: • For each class, it is required to implement constructors, setters, getters, toString() method, and any other necessary method • If the user tries to do an operation that could violate the state of objects, the operation should be ignored and the application should display an error message (e.g. adding a passenger to the same trip twice, etc.) Checking equality of any 2 objects should be done via the equals() method • • Testing: After implementing the required classes, design and implement a testing class to test them as follows: There is a class that will do the main job of as follows: o It has one collection to store the whole data (all trips) o It has static methods, one for each operation happens frequently o For each adding or removing operation, a message should be displayed to the user to explain the status of the operation (i.e. if it was successful or not) • Create at least 7 trips in at least 3 different dates and add them to the collection that stores the whole data…2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.Dice Rolling Class In this problem, you will need to create a program that simulates rolling dice. To start this project, you will first need to define the properties and behaviors of a single die that can be reused multiple times in your future code. This will be done by creating a Dice class. Create a Dice class that contains the following members: Two private integer variables to store the minimum and maximum roll possible. Two constructors that initialize the data members that store the min/max possible values of rolls. a constructor with default min/max values. a constructor that takes 2 input arguments corresponding to the min and max roll values Create a roll() function that returns a random number that is uniformly distributed between the minimum and maximum possible roll values. Create a small test program that asks the user to give a minValue and maxValue for a die, construct a single object of the Dice class with the constructor that initializes the min and max…
- Paper Scissors Rock “Strategy” Purpose:To review class inheritance. Directions and Examples:Download the starter code from the dropbox where you got this assignment. This code contains a class called Player that randomly chooses paper, scissors or rock with equal probability. It also contains a class called PaperScissorsRock that creates two Player objects, has them play one million games, and counts the number of times Player 1 wins. Your task for the practice lab is to create a subclass of Player called StrategicPlayer. The StrategicPlayer class should have the following fields and methods:private double percentPaper – the likelihood (between 0 and 1) that the player will choose paperprivate double percentScissors – the likelihood (between 0 and 1) that the player will choose scissorsprivate double percentRock – the likelihood (between 0 and 1) that the player will choose rockpublic StrategicPlayer(double paper, double scissors, double rock) – a constructor that initializes the…Class members are private by default and it's not possible to access them outside the class.

- Pyhton Code: Create a Pizza class which stores information about a single pizza. It contains the following: -Instance variables to store the size of the pizza (small, medium or large), (1)the number of cheese toppings, (2)the number of pepperoni toppings, and the (3) number of mushroom toppings. - Constructor: that takes four arguments and sets all of the corresponding instance variables and that initializes all instance variables to the zero of their type. - Methods to get (accessor) and set (mutator) each instance variable individually. - A method called calcCost() that returns the cost of the pizza. Pizza cost is determined by: Small: $10 + $2 per topping Medium: $12 + $2 per topping Large: $14 + $2 per topping. -A method which returns a string for the pizza size, quantity of each topping, and the pizza cost as calculated by the following example, a large pizza with 1 cheese, 2 pepperoni and 1 mushroom toppings should cost $22 (you can overwrite __str__).Method,Field can be accessed from the same class to which they belong.Dynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100. Next, dynamically create a Game object (remember that this…
