- 1/ Implement a class Employee. An employee has a name (a string) and a salary (a double). Provide a constructor with two arguments public Employee(String employeeName, double currentSalary) and methods public String getName() public double getSalary() public void raiseSalary(double byPercent) These methods return the name and salary, and raise the employee's salary by a certain percentage. Sample usage: Employee harry = new Employee("Hacker, Harry", 50000); harry.raiseSalary(10); // Harry gets a 10 percent raise Supply an EmployeeTester class that tests all methods. 2/Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a method drive that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank. Also supply methods…Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, “see the dentist”) and a date (use int's to store the date). Write a method occursOn(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Additionally, you will need to implement a class called Calendar. This will contain an ArrayList of Appointment objects (The list is an instance variable of the Calendar class). You will need to provide the following methods for your Calendar class. A no argument constructor public Calendar(){...} This constructor will initialize your ArrayList instance variable to an empty list. /** * A method to add an appointment to the calendar * @param apt – the appointment object to add to the calendar. */ public void add(Appointment apt) {…} /** * A method to remove an appointment from the…a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type: 1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z. Example Output(x, y, z): (1, 2, 3)(x, y, z) : (0, 0, 0)
- IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…Implement the design of the Patient class so that the following output is produced:[For BMI, the formula is BMI = weight/height^2, where weight is in kg and height inmeters] Driver Code # Write your code herep1 = Patient("A", 55, 63.0, 158.0)p1.printDetails()print("====================")p2 = Patient("B", 53, 61.0, 149.0)p2.printDetails() Output1/ Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance.

- Implement a class Season that represents a season during a specified year. For purposes of thisproblem, assume that the seasons in each year are, in order, 'Winter', 'Spring', 'Summer', 'Autumn' .__init__, __repr__A Season object is created by calling the constructor and supplying two optional arguments:1. season, defaults to 'Winter'2. calendar year, an int , defaults to 2023For the __repr__ , see the usage below: The next and prev methods modify a Season object by changing it to the next season or previousseason in sequence, respectively. Note that the seasons can "roll over" or "roll back" and that this maychange the year by +/-1. 1. During each year, the seasons occur in this sequence: 'Winter', 'Spring', 'Summer', 'Autumn' 2. next - change to next season, if the current season is Autumn then year will increase by 1 3. prev - change to previous season, if Winter then year will decrease by 1 Implement the == operator ( __eq__ method) to compare two Season…Write a Java program with at least two classes. Use a circle object to represent it. The class must offer at least one (non-static) setter method and one (non-static) getter method. Implement at least one test that invokes the setter method and the corresponding getter method so that the value out == the value in. Also use assert.Equal(60, circle1.getCircumference(), 10); and assert.Equals(10, circle1.get Radius(), 0.1); for radiusAdd the following methos to the class Person(code bellow) in Python: a) Add a method isDescendant(personID) to Person which takes a person identifier string as an argument and returns True if the identified person is an descendant of self or False if this is not the case. The answer should be True when the identified person is self. b) Add a method printAncestors() to Person that does what its name suggests. You aren't likely to manage to make this look as good as the output of printDescendants, but each line should include some indication how many generations up the tree the ancestor is. Just starting the line with a number and appropriate indentation is sufficient. from collections import namedtuple class Person(): # Stores info about a single person # Created when an Individual (INDI) GEDCOM record is processed. #------------------------------------------------------------------- def __init__(self,ref): # Initializes a new Person object, storing the string…
