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:
Which one of the following statements is true?
In Java, super, base, and parent are all synonyms when discussing inheritance.
In Java, child, sub, and derived are all synonyms when discussing inheritance.
In Java, all classes are derived from the Object class.
All of the above are true statements.

- Find the syntax errors in the following class definition. Indicate the errors and state why there is an error.A Java-supplied default (a.k.a. a no-argument, or no-args) constructor (i.e., a constructor that takes no parameters and essentially does nothing) is automatically generated by Java for a class, provided that no other constructor is defined for the class. * True FalseSelect the answer that best describes the following statements: I. A class is an instance of an object. II. A reference type does not store data directly but points towards some data. O Only statement I is true Only statement II is true Both statements I and II are true Both statements I and II are false
- Write C# equivalent statements for the following: An “Account” class will be created having properties: accountName, accountNumber, accountType, totalBalance and methods: WithdrawAmount(), CheckBlance(), DepositAmount(). Derive child classes, that is, “SavingAccount” and “CurrentAccount” from the Account class and implement the following functionality. While taking input from user, check whether the account type is Saving or Current. If user enters “Saving”, an object of Saving Account will be instantiated and while depositing amount in the account an extra 3% of the amount will be deposited (as an extra profit) with the actual amount entered by user. If user enters “Current”, an object of Current Account will be instantiated and while depositing amount in the account, no extra amount will be deposited. Only the actual amount will be deposited. Also implement all the methods mentioned above.PLEASE USE 2 CLASSES (you do not have to answer quickly please take your time) In the Game of 21, a player is dealt two cards from a deck of playing cards and then optionally givena third card. The player closest to 21 points without going over is the winner. Use object-orienteddevelopment to create a Game of 21 application that allows the user to play the Game of 21 against thecomputer. The Game of 21 application and its objects should:• Deal a card from a deck of playing cards by generating a random number between 1and 13. A 1 corresponds to an Ace, numbers 2 through 10 correspond to those cards,and 11 through 13 corresponds to Jack, Queen, and King. The Jack, Queen, and Kinghave a value of 10 in the Game of 21. An Ace can have a value of either 1 or 11.• Allow the player to stay with two cards or be given a third card.• Announce the winner.• Play rounds until the player says to stopIn Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!
- Please help me solve it today I posted it yesterday and got rejected I don't know why:( Please help me solve this with Java Game class instructions:• Game class has three attributes: points (which represent the number of points awarded when winning the game), status (false if the game has not been played and true if the game has been played), and description (which is a text description of the game). Note that description attribute is a read-only variable. • In the constructor, initialize points to zero, status to false, and description to the given parameter.• isPlayed method returns true if the game has been played, and false otherwise.• getPoints is a getter method for points attribute.• play method is an abstract method.• Override toString method to return the game description.• Override equals method so that two games are the same if their descriptions are the same. :instructions class ) HangMan• HangMan is a game in which a player tries to guess a word based on a given hint.…Which statement of the following is the most appropriate?

- In C++ by using all header files and source files construct this: Create a Human class with the following features: Each Human needs a name, an age, and some phrase that they say. Each Human needs appropriate getters and setters for all attributes. For every interaction with this human, increment the age by 1 year. Default constructor with no arguments. Constructor that takes name, age, and phrase arguments. Create a driver to demonstrate all of the features of your Human class. The driver is the only class with main().The driver must create a dynamic array of Human Objects of some user defined size. This requires prompting the user for a number of Humans to create.Be sure to iterate through your array of Humans. Interact with every Human object. Demonstrate ALL features of the Human class. The Human class must to be defined in a header file with no implementation. Additionally, create an implementation file with all of the Human implementation code.1. Which of the following statements is TRUE about classes, objects, and constructors? A. An object is a blueprint for a class. B. A class can have multiple constructors. C.
