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:
The Instantiation keyword is a Java operator that creates the object.It is also known as instantiating a class.

- C# A(n) __ is a method that is automatically executed when an object is created. Question 3 options: instantiation header declaration constructorA method that returns the value of an object's instance variable is calleda(n)a) mutator b) function c) constructor d) accessorCreate an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make private string model private string color private int year private int mileage Your program should have appropriate methods such as: default constructor parameterized constructor add a new vehicle method list vehicle information (return string array) remove a vehicle method update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values. Loop through the array and print to the screen.…
- 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.One or more objects may be created from a(n) A. method B. instance C. class D. fieldAttached you will find a Java class called Employee. This class includes a constructor which sets name to blanks and salary to $0.00 and a constructor which sets name to a starting name and salary to a set amount. Additionally, the class includes methods to set the name and salary and return the name and salary. You will create a new class called Manager that inherits from the attached class Employee. Add a field named department of type String. Create a get and set method for the department variable. Supply a method toString that prints the manager's name, department, and salary. But you may not change anything in the Employee class. You will then create a test class that uses the Manager class. The test class should prompt the user to enter name, department and salary. This information should be stored in an array. Upon entry of an employee records, the program should output the information you entered.
- If we do not override the toString method in a class, the toString method for the Object is called. The default output is <class name>@<memory location>. True FalseFocus on classes, objects, methods and good programming styleYour task is to create a BankAccount class using Python and Write an overall header comment for every function - use the IPO notation. Class name BankAccount Attributes __balance float float __pin integer integer Methods __init_() get_pin() check_pin() deposit() withdraw() get_balance() The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0.get_pin()should return the pin.check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not.deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance.withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return…A __________ is a variable that is declared inside a class but not inside any method. a. term b. class variable c. field d. mnemonic
- a- Write a java class named Account which contains: private data field named number of type int private data field named balance of type double no argument constructor An argument constructor to create Account object with specified number and balance. A method toString() that returns number and balance as a String Set and Get Methods for all the data fields b- Write java code for the test class named testAccount which contains: Main method Create this object of type account à number:30214 balance:950.23 Change the balance by using set method to 900.0 Print the object by using toString method.Car ClassWrite a class named Car that has the following fields:• yearModel. The yearModel field is an int that holds the car’s year model.• make. The make field references a String object that holds the make of the car.• speed. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods.• Constructor. The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.• Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.• accelerate. The accelerate method should add 5 to the speed field each time it is called.• brake. The brake method should subtract 5 from the speed field each time it is called.Demonstrate the class in a program that creates a Car object, and then calls the accelerate method five…Focus on classes, objects, methods and good programming styleYour task is to create a BankAccount class.
