1.Write a class named Car that has the following data attributes:(a.) __year_model (for the car’s year model)__make (for the make of the car)__speed (for the car’s current speed)The Car class should have an __init__ method that accepts the car’s year model andmake as arguments.These values should be assigned to the object’s __year_model and __make dataattributes.It should also assign 0 to the __speed data attribute.The class should also have the following methods:(b). Accelerate: The accelerate method should add 5 to the speed data attributeeach time it is called.Brake: The brake method should subtract 5 from the speed data attribute eachtime it is called.get_speed: The get_speed method should return the current speed
Which of the following statements are correct? (Select all that applies.) Group of answer choices a) Inheritance is the process by which one object can acquire the properties of another object. b) "super" is used to access the method or member variables from the parent class. c) Constructors are used to initialize a newly created object. d) Method overriding occurs when a child class declares a method that has the same type of arguments as a method declared by one of its parent classes. e) An object that has more than one form is referred to polymorphism.
Question: Choose the correct one. Note: Give me all the answers without explanation. 1.It is an instance of the class Select one: a. Method b. Object c. Data member d. Constructor 2.The encapsulation concept means. Select one: a. The class has private constructors and methods b. The data members are public access c. The data members are private access d. you can't access the members of the class even from the class itself 3.char A[]="hahahah"; char* p=&A[0]; *p='na'; p="CII"; cout<<A; the output is. Select one: a. CIIhahahah b. hahahah c. aahahah d. nahahah 4.Let A is char array as follows: char A[]=”hahahah”; the length of A Select one: a. 32 characters b. 7 characters c. 28 characters d. 8 characters 5.class A{int x;}; class B:public A{int y;public: void add(){y=++x;}};to correct the error. Select one: a. We should use protected: in class A b. We should use private: in class A c. We should use protected: in class B d. We should use public: in class B…
Indicate whether the statement is true or false. 13. The non-static methods of a class are called instance method. 14. A constructor has no type and is therefore a void method. 15. A class can have only two constructors. 16. In shallow copying, each reference variable refers to its own object. 21. The method finalize automatically executes when the class objects goes out of scope. 22. A mutator method of a class changes the values of data members of the class. 23. In java, the reference this is used to refer to only the methods, not the instance variables of a class. 24. Classes that are defined within other classes are called inside classes. 25. Modifiers are used to alter the behavior of the class 26. A constructor has the same name as the class. 27. Constructors are called like any other method. 28. You can perform some arithmetic operations on class objects.
a) Create an enumeration named Departments that contain four set of values FINANCE, HR, IT, and MARKETING.b) Create a class named PersonDetails that contains fields for a person’s first name (String), last name (String), and address (String). The class have- A constructor that accepts parameters for each field.- Get methods for each field.c) Create a class named Employee that contains fields for an employee ID (int), Social Security number (String), personal information (Person object), department (Departments type), and annual salary (double). The class have- A constructor that requires values for each data field.- Get methods for each of the data fields.- Set methods for each of the data fields.d) Create an application/class named EmployeeSort that allows a user to enter values for an array of 5 Employee objects (create an array of Employee type that will save 5 employee objects). Prompt a user for the data needed to create an employee object. Continue to prompt the user for Social…

not handwritten Which of the following are NOT true for a constructor? Select one: a. It does not return anything b. Every class must include an explicitly written constructor c. Every field in the class is initialized in the constructor. d. It must have the same name as the class
The question #1 should be read as: hasValidPassword method that checks and return true if the password is not the same as username and it does not contains the user id Question #2 should accept only 3 parameters instead of 4. But it will have the 4th parameter for output. 3 input parameters + 1 output parameter + integer return code. IN C++ • All data members must be declared as “private” • No global variable is allowed to be declared and used • Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and return value instead. • “cin” and “cout” should be done in main() or any testing functions • Make sure that you clearly show how the C++ class, its methods and all the functions are being called at least twice and print out its return value and its results properly.
1) Change the visibility of the variables and constructor in the Employee class to be more secure 2) Add an Admin class with the following features: a) The Admin class is a child of the Employee class b) Admin objects have an instance string password variable c) The Admin class has a 4 parameter constructor. One parameter sets the string, the other three parameters are used as arguments for a parent constructor call. d) Admin objects have an instance getInformation() method with a void return and an Employee object parameter. The method will request the calling Admin’s password and check user input. If input matches the password, the method will display the information of the Employee parameter Please use ***C Sharp** Language to answer the code
JAVA QUESTION REQUIRES SEPARATE CLASSES, CANNOT BE WRITTEN IN ONE MAIN METHOD E.G. ACCOUNT SECTION WRITTEN IN ACCOUNT CLASS, CUSTOMER SECTION WRITTEN IN CUSTOMER CLASS ETC. Phase 2 In this phase you’ll be writing code within the methods of your classes to make the tests pass. Account Each account should have a constant, unique id. Id numbers should start from 1000 and increment by 5. The ACCOUNT_ID attribute should be initialised when the account object is created. The id should be generated internally within the class, it should not be passed in as an argument. The deposit method should increase the balance by the value passed in as an argument. The withdraw method should reduce the balance by the value passed in as an argument. It should return the value of the argument The account should be able to go overdrawn The correctBalance method should change the balance to match the value passed in as an argument. Testing your code for Account Run TestAccountInitialisation to check…
