True or FalseIt is a common practice to make all a class’s fields private and to provide access to those fields through methods.
Given these three arguments, please explain why it is better to have accessors for private types rather than making them public.
In java, can a polymorphic reference invoke a method that is only declared at the object's class level? If "yes", explain how.

It has a constructor that takes SID as a parameter. The Main class is used to declare objects from the Student class. The Main method should take student of type Student then display student ’ ’ s data from the console, store them in an object s data in the console.arrow_forward
- Is it true that when a method gets an object as a parameter, it has access to the original object or a duplicate of it?arrow_forwardReuse your Car class . In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…arrow_forwardJava- Suppose that Vehicle is a class and Car is a new class that extends Vehicle.

An accessor is also known as a setter methodarrow_forwardComplete the equals method in the AbstractShape class. The equals method should take an Object parameter, compare two instances of the AbstractShape class, and return true if all instance variable data matches.arrow_forwardWrite in python. Write a class named Employee that has **private** data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address.Write a separate function (not part of the Employee class) named **make_employee_dict** that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary.For example, it could be used like…arrow_forward
