- Pick an object around you and create a class out of it - plan your class (Name, Parameters, Functionality) - your object has to have at least 4 parameters ( 2 string, 2 numbers) - your data has to be private - implement (override) the function __str__ to show the relative information for your function - create at least one extra function in your class for the object - create 4 different objects from your design class This question is based on python.A(n) ___ provides abstract methods and no other code. abstract class interface polymorphic class base class The _____ component allows the user to navigate directories and select a file. JFileFind JFileSystem JFileDir JFileChooser A stack overflow typically causes a program to _____. return a value crash give multiple outcomes give an incorrect outputFocus on classes, objects, methods and good programming styleYour task is to create a BankAccount class using Python.

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argument, add the amount to the account and return the new balance.withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was…
- Python Programming1.Write a class named Car that has the following data attributes:(a.) __year_model (for the car’s year model)__make (for the make of the car)__speed (for the car’s current speed)The Car class should have an __init__ method that accepts the car’s year model and make as arguments. These values should be assigned to the object’s __year_model and __make data attributes. It should also assign 0 to the __speed data attribute.The class should also have the following methods:(b). Accelerate: The accelerate method should add 5 to the speed data attribute each time it is called.Brake: The brake method should subtract 5 from the speed data attribute each time it is called.get_speed: The get_speed method should return the current speedIn Java, inheritance is a mechanism that allows a subclass to ________ the properties and methods of a superclass.Data structure & Algrothium java program Create the following classes: 1. Name.java object class containing two strings attributes first name and last name (and appropriate constructors, setters/getters)2. NicePerson.java object class containing the name object and an ArrayList of string to store the list gifts ( and appropriate constructors, setters/getters). This class would extend the attached NicePersonInterface.java3. Santa.java object class containing one ArrayList of Names to store the naughty names. Another ArrayList of NicePerson to store the nice names and gifts. Add atleast 4 names in each list and display all information.

Select one: O True OFalse Encapsulation is the process of grouping the attributes and method of an object together in a single data structure known as a class Select one: O True O False A constructor is a member variable that is called automatically when an object is created. Select one: O True O False We cannot declare more than one constructor per class. Select one: O True O False onFocus on classes, objects, methods and good programming style.
