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:

- Create a program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p)Implement the following concepts by constructing suitable classes in Java -a. Constructorsb. Constructor Overloadingc. Function Overloadingd. Function Overridinge. InheritanceCreate a class Person - Field - Name, Birthdate, Contact no and Mail idMethods - Constructor, accept and displayClass Employee - Inherits the Person classFields : Emp ID, grade, basic salary, Gross Salary, HRA (House Rent Allowance), TA (TravelingAllowance), DA (Dearness Allowance)Given:Grade Basic TAA 8000 2000B 7000 1500C 6000 1000D 5000 500Calculate Gross Salary :Gross Salary = Basic + HRA (20% of Basic) + DA (50% Basic) + TAe.g if Basic = 8000TA = 2000HRA = 20% of 8000 = 1600DA = 50 % of 8000 = 4000Gross = 8000 + 2000 + 1600 + 4000 = 15600Optional : you can implement increment function in which you can change grade of an employee andrecalculate salary with new gradeIf class A is a subclass of class B, then A has access to all of B's instance variables, including private ones.

Give the line number containing the constructor that is executed in each of the following declarations: (i) CC one = new CC( ); _________________ (ii) CC two = new CC(5, 6); _________________ (iii) CC three = new CC(2, 8, 3.5); _________________ B. Write the definition of the constructor in Line 1 so that the instance variables are initialized to 0.

Both classes (CurrentAccount and SavingsAccount) inherit all attributes/behaviors from the BankAccount class. In addition, followings are required to be the part of both classes• Appropriate constructors to initialize data fields of base class• A function named amountWithdrawn(amount) to withdraw certain amount while taken into account the following conditionso While withdrawing from current account, the minimum balance should not decrease Rs. 5000o While withdrawing from savings account, the minimum balance should not decrease Rs. 10,000• amountDeposit(amount) to deposit amount in the accountIn the main() function, create instances of derived classes (i.e. CurrentAccount and SavingsAccount) and invoke their respective…
- Consider a base class named Employee and its derived classes HourlyEmployee and PermanentEmployee while taking into account the following criteria.• Employee class has two data fields i.e. a name (of type string) and specific empID (of type integer)• Both classes (HourlyEmployee and PermanentEmployee) have an attribute named hourlyIncome• Both classes (HourlyEmployee and PermanentEmployee) have three-argumentconstructor to initialize the hourlyIncome as well as data fields of the base class• Class HourlyEmployee has a function named calculate_the_hourly_income to calculate the income of an employee for the actual number of hours he or she worked. One hour income is Rs. 150 • Similarly, PermanentEmployee class has function named calculate_the_income to calculate the income of an employee that gets paid the salary for exact 240 hours, no matter how many actual hours he or she worked. Again, one hour salary is Rs. 150.Implement all class definitions with their respective constructors to…Consider the following class implementation, which represents a price in dollars and cents: class Price { private: int dollars; int cents; public: Price() { dollars = cents = 0; } Price(int d, int c) { dollars = d; cents = c; } bool operator!=(Price); bool operator<(Price); }; Write an implementation for both overloaded operators. != should return true if the Prices are not equivalent, and should return false if they are equivalent. < should return true if the Price of the calling object (left object) is less than the parameter Price object (right object). You do not need to demonstrate calling these operators.1) Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; It asks to create an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. Assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You don't need to demonstrate calling these operators.
- Convert the UML class diagram above into a java code with the following conditions The methods in the Pet class are abstract. Create a class called test. The main() method in the test class should create three Cat objects and two Budgie The main() method should also create indirectly an object of the Pet class. Demonstrate polymorphism in your testModel a room class, whose member data is three integers length, width and height. The classcontains two constructors to initialize the room class objects, first is no argumentconstructor, while the second in three arguments constructor. Class also contains threemember functions i.e., getdatat) to get the data from user and store in the memory of callingobject and showdata) to show the room data of calling object, int volume(int I, int w, int h)function should receive the length, width and height values from the objects one by one andreturn the volumes of the three objects respectively.Write a main program to declare the three object rl, 12, and 13 of room class. Two objectwill store the values through three argument constructor and third object will get the datafrom user by calling getdata function. Then all three objects should call the volumefunctions to calculate their volumes and store them in three variables of type integer. Finallythe system compare the three volumes values…Consider the definition of the class product Type as given in Exercise 8. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the function set so that instance variables are set according to the paramaters. Instance variables quantitieslnStock, price, and discount must be nonnegative. b. Write the definition of the function print to output the values of the instance variables. c Write the definition of the function setQuantitiesInStock to set the value of the instance variable quantitiesInStock according to the parameter. d. Write the definition of the function updateQuantitiesInStock to update the value of instance variable quantitiesInStock by adding the value of the parameter. e. Write the definition of the function getQuantitiesInStock to return the value of instance variable quantitiesInStock. f. Write the definition of the function setPrice to set the value of the instance variable price according to the parameter. g. Write the definition of the function getPrice to return the value of the instance variable price. h.
