- 2. Suppose class called Student that defines three instance variables: name (string), age (integer), mark1, mark2 and mark3 (double) And three methods: readinfo for read data for student. printlnfo for print student name and average. average for return average of three marks (mark1, mark2 and mark3). Write a program that test methods in the class.Java. Modify a dealership's Automobile class so it includes fields for an id (ID number), make, model, color, year, and mpg (miles per gallon). Include get and set methods for each field. Do not allow the ID to be negative or more than 9999; if it is, set the ID to 0. Do not allow the year to be earlier than 2005 or later than 2019; if it is, set the year to 0. Do not allow the miles per gallon to be less than 10 or more than 60; if it is, set the miles per gallon to 0. Include a constructor that accepts arguments for each field value and uses the set methods to assign the values. The TestAutomobile.java file has been provided to test your implementation. Here is the code so far: public class Automobile { private int id; private String make; private String model; private String color; private int year; private double mpg; public Automobile(int id, String make, String model, String color, int year, double mpg) { } public…Java.

- Write a program in java Design a class that holds the following personal data: name, address, age, and phone number.Write appropriate accessor and mutator methods. Demonstrate the class by writing aprogram that creates three instances of it. One instance should hold your information, andthe other two should hold your friends’ or family members’ information.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…Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods.

- The following is a class definition for a simple Ebook. Two instance variables and one parameterless constructor are provided. Part 1: Write a second constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the current page number to zero. Part 2: Write a getter and a setter method for the page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. public class Ebook{ private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; }}Python Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 this is what I have but its not working: class Car:def __init__(self):self.model_year = yearself.purchase_price= priceself.current_value = 0 def calc_current_value(self, current_year):depreciation_rate = 0.15# Car depreciation formulacar_age = current_year - self.model_yearself.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)return self.current_valuedef print_info(self,current_value):print("Car's information: Model year: ",self.model_year,"Purchase price: ",self.purchase_price,"Current value: ",self.current_value) if __name__ == "__main__": year = int(input()) price =…Methods in Java Write a program that accepts three strings: first name, last name, age, and nationality. Create an object of the class Person and assign the inputs to their respective attributes. In the class, create a method greeting() that prints the attributes. Inputs 1. Input Cody Chum 20 Filipino Sample Output Enter first name: Cody Enter last name: Chum Enter age: 20 Enter nationality: Filipino Hello, I am Cody Chum, 20 years old and a Filipino!
- write a java program This composition example contains classes Date, Employee and EmployeeTest .Class Date declares instance variables month, day and year to represent a date. The constructor receives three int parameters. It has checks to validate the month—if the value is out-of-range the method throws an error message, same goes for day. Provide getters, setters and toString method. Class Employee has instance variables firstName, lastName, birthDate and hireDate. firstName and lastName are references to String objects. Members birthDate and hireDate are references to Date objects. • The Employee constructor takes four parameters—first, last, dateOfBirth and dateOfHire. Initialize the hireDate and birthDate with these objects by calling its constructor and setters. • When class Employee’s toString method is called, it returns a String containing the employee’s name and the String representations of the two Date objects. Each of these Strings is obtained with an implicit call…Write a program that test methods in the class. • Hint: the employee deserved retirement if he has year of Service >25 or his age >=65. 5. Design a class named MyInteger. The class contains: • An int data field named value(int) Methods isEven() and respectively. Write a program that test methods in the class. isOdd() that return true if the value is even or odd.write a c++ program Write a class Date that represents a date consisting of a year, month, and day. A Date classshould have the following methods:# Date(int year, int month, int day)Constructs a new Date object to represent the given date.# void add(int &days)Moves this Date object forward by the given number of days. hint:* you should decideon the basis of month and year that given month ends 30,31,28,29 days.# void add(int &month , int &days) Moves this Date object forward by the given number of months and days. Monthsshould be within 1 to 12 and days in 1 to 31.
