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:
basic java only

- 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…Design a class called Date that has integer data members to store month , day, and year. The class should have two constructors; a default constructor that accepts no parameters, and a three-parameter constructor that allows the date to be set by the programmer. If the user creates a Date object without passing any arguments, or if any of the values passed are invalid, the default values of 1, 1, 2001 (i.e., January 1, 2001) should be used. The class should have three (3) member functions to print the date in the following formats: 3/15/16 March 15, 2016 15 March 2016 Demonstrate the class by writing a program that uses it. Be sure your program only accepts reasonable values for month and day. The month should be between 1 and 12. The day should be between 1 and the number of days in the selected month. I expect to see all uses of the constructors that you made, including the error checking. I also expect to see all uses of the 3 output functions in your program. You are responsible…Create a class named Employee which contains an employee name, available to the entire program (public), and an employee ID number and hourly pay rate, available only to the members of the Employee class (private). Also write a constructor (the __init__ member function) which accepts a pay rate and changes it to 7.25, if the value entered is less than that. Do not write any accessor or mutator methods for the class.
- Create a class named Employee. The class must contain private member variables: name and salary. It should contain getter methods for returning the name and salary. It should also contain setter methods for setting the name and salary. The class must include a constructor, the constructor must be designed to set both the name and the salary. In addition, the Employee class must contain a toString() method that prints both name and salary. Create a class named Test. The class must contain the mainmethod. In the main method, you should create three objects fromclass Employee and store them in an array of type Employee (youmust prompt the user to enter name and salary for each object).Then, you should print the name and salary of each object (usingeither the getters or the toStrong() method). DO NOT COPY CHEGG1- Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the radius variable, and a function named getArea that returns the area of the circle. The area is calculated as 3.14159 * radius * radius 2- Add a default constructor to the Circle class in question (1). The constructor should initialize the radius member to 0 3- Add an overloaded constructor to the Circle class in question (2). The constructor should accept an argument and assign its value to the radius member variableQ2. Write a class Bank that has the following data members –Account Holder name (ah_name[]) –Account number (ac_number) •Must unique, system generates automatically, and must starting from 100 (Hints: Use another static variable and assign that variable to ac_number) –Balance in the account (ac_balance) •The class has the following member functions –A constructor to initialize the data members –Input() to takes name from the user –Deposit(parameter) to deposits balance in the account •Must accept parameter (The amount to deposit) –Withdraw(parameter) to withdraws balance after checking •Must accept parameter (The amount to withdraw) –Display() to show the name, account number, and balance
- Create a class Car, which contains • Three data members i.e. carName (of string type), ignition (of bool type), and currentSpeed (of integer type)• A no-argument constructor to initialize all data members with default values• A parameterized constructor to initialize all data members with user-defined values• Three setter functions to set values for all data members individually• Three getter function to get value of all data members individually• A member function setSpeed( ) // takes integer argument for setting speedDerive a class named Convertible that contains• A data member top (of Boolean type)• A no-argument constructor to assign default value as “false” to top• A four argument constructor to assign values to all data-members i.e. carName, ignition,currentSpeed and top.• A setter to set the top data member up• A function named show() that displays all data member values of invoking objectWrite a main() function that instantiates objects of Convertible class and test the…Create a class Car, which contains • Three data members i.e. carName (of string type), ignition (of bool type), and currentSpeed (of integer type) • A no-argument constructor to initialize all data members with default values • A parameterized constructor to initialize all data members with user-defined values• Three setter functions to set values for all data members individually• Three getter function to get value of all data members individually• A member function setSpeed( ) // takes integer argument for setting speedDerive a class named Convertible that contains • A data member top (of Boolean type) • A no-argument constructor to assign default value as “false” to top• A four argument constructor to assign values to all data-members i.e. carName, ignition, currentSpeed and top.• A setter to set the top data member up • A function named show() that displays all data member values of invoking objectWrite a main() function that instantiates objects of Convertible class and test the…JAVA - USING CONSTRUCTORS Create a class named House that includes data fields for the number of occupants and the annual income as well as methods named setOccupants(), setIncome(), getOccupants() and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and income field to 0. Create an additional overloaded constructor . This constructor receives an integer argument and assigns the value to the occupants field. Create a third overloaded constructor this time, the constructor receives 2 arguments, the values of which are assigned to the occupants and income fields respectively. Create another class named I_house that instantiates the House class and see if the constructors work correctly.
- 2- Create a class time24, each object is a value represented the time ofday in the form hours, minutes and seconds. Provide a constructorthat enables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in case noinitializes are provided.Provide Public member functions for each of the followingoperations: set the time, print the time, increment the time by onesecond, compare two times for equality, increment the time by onehour, determine if one time is “less than” (comes before) anothertime, and final print the time in format 12 hours.Include any additional operations that you think would be useful foryour class.Design, implement, and test your class.Create a base class called Vehicle with name, max_speed, and tank_size attributes. Then create a derived class called Truck that inherits from the Vehicle class. The Truck should have an additional attribute called seating_capacity with default value of 5. The child class should have a method named range to calculate fuel efficiency - the calculation should be: max_speed * seating_capacity * tank_size. Override the method such that it can accept 1, 2 or 3 positional arguments. Attached is my following code, also attached is a method for override method. Need help implementing the override method for the range to calculate the fuel effiency.Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
