Create an application named CarDemo that declares at least two Car objects and demonstrates how they can be incremented using an overloaded ++ operator. Create a Car class that contains a model and a value for miles per gallon. Include two overloaded constructors. One accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20. Overload a ++ operator that increases the miles per gallon value by 1. The CarDemo application creates at least one Car using each constructor and displays the Car values both before and after incrementation.
Question 1 ( Java Programming)1. Create a class called Parents with private variables of type String, mother and father, and also two private variables for their birthday year in type integer. (a) Create a constructor to initialize all four variables. (b) Create another constructor (overloading) to initialize variables mother and father only. (c) Create getters and setters for the variables. (d) Create a method called parentsAge which display your parents’ age based on the birthday year that you input in the test class. 2. Create a child class for Parents called Siblings (a) Create two variables called brother and sister of type String. (b) Create a constructor to initialize all variables including the variables from Parents class. All together there should be six number of arguments. (c) Create another constructor (overloading) that initialize all the variables including variables from Parents (minus the age). All together there should be four number of arguments. (d) Create a method…
Python Class and Objects 1. Create a class named "Account" and “Bank” 2. The class “Account” should have a parameter of id - integer type name - string type balance - float type # (Optional) You may add more parameters for your convenience 3. Create a method for “Account” class: checkBalance(self) - this will show the Account's remaining balance or money withdraw(self, amount) - this will withdraw an amount from the Account deposit(self, amount) - this will deposit an amount from the Account # (Optional) You may add more methods like sendMoney() etc.
Please code in python Create a program with two classes – the person class and the student The person class has the following properties: first name (first_name), last name (last_name) street address (address) city (city) zip code (zip) The class has the following methods: get_full_name, which returns the full name of a person get_full_address, which return greeting, returns a greeting message. The class should provide accessor and mutator for each property The class should override the __str__ method to return the state of the object. Create a child class called student which has a property named graduation year (graduation_year) and major. Provide accessor and mutator for each property of its own It inherits all the properties and methods of the person parent class as well. Create a test program that Create an object of the person class and print the full name of a person. Create an object of the person class and print…
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.
CREATE IN JAVA PLEASE 1. Create a class named Taxes.2. Create two instance variables, one variable named taxDue and the other taxBracket. Bothinstance variables should be double.3. Create a constructor that has an argument type double named tb. Initialize the taxDue tozero and the taxBracet to tb.4. Create a method named calculateTaxDue. The method should not return anything andshould have two arguments, both doubles. One argument should be totalIncome and theother should be taxPaid.5. The calculateTaxDue should multiple the totalIncome by the taxBracket and assign it to alocal variable named calcTax.6. The calculateTaxD should subtract calcTax from taxPaid and assign it to taxDue.7. Create a method to return taxDue.1. Create a tester class.2. Import Scanner.3. Add the plumbing.4.

The default values are 1 for both width and height.b. A no-arg constructor that creates a default rectangle.c. A constructor that creates a rectangle with the specified width and height.d. A method named getArea() that returns the area of this rectangle.e. A method named getPerimeter() that returns the perimeter. in Java
a. Create a class named Invoice that contains fields for an item number, name, quantity, price, and total cost. Create instance methods that set the item name, quantity, and price. Whenever the price or quantity is set, recalculate the total (price times quantity). Also include a displayLine() method that displays the item number, name, quantity, price, and total cost. Save the class as Invoice.java. b. Create a class named TestInvoice whose main() method declares three Invoice items. Create a method that prompts the user for and accepts values for the item number, name, quantity, and price for each Invoice. Then display each completed object. Save the application as TestInvoice.java.
JAVA Design a class named MyInteger. The class contains: An int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int A get method that returns the int Methods isEven(), isOdd(), and isPrime() that return true if the value is even, odd, or prime, respectively. Static methods isEven(int), isOdd(int), and isPrime(int) that return true if the specified value is even, odd, or prime, respectively. Method equals(int) that return true if the value in the object is equal to the specified value.
Using Java Create a constructor named Exam that assigns "Good luck" to a previously declared String variable named message. Create an empty overloaded constructor for the Exam class with two (2) String parameters named period and level. Declare a double-type accessor named getPrice that returns the value of price. Declare a boolean-type accessor named isFinished that returns the value of status. Declare a class named Midterm that inherits from the class named Exam. Create three (3) class declarations to show multiple levels of inheritance. Use the classes named Exam, Midterm, and Essay. Create a constructor named Midterm that prints "Exam has started." using println(). Its first statement should be a call to a constructor in the parent class. Given the base class named Quiz and the derived class named Essay, write a statement to show inheritance between these classes.
