Define a class namely RegularAcc for online shopping with attributes name (string), balance (double), and a method as below boolpay(double amount): to pay and deduct from the current balance (false if does not have enough money). Define another class GoldAcc inherits from the class RegularAcc, with an extra attribute namely bonusCoin (double). Override the pay method for GoldAcc so that 5% of paying amount will be rewarded to the bonusCoin. Example: paying amount = $1000 → reduce $1000 from current balance and add $50 to the bonusCoinvalue. Provide suitable constructors and test pay() methods of both RegularAcc and GoldAcc classes in main().
Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g…
a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type: 1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z. Example Output(x, y, z): (1, 2, 3)(x, y, z) : (0, 0, 0)
In this challenge, we'll implement an Account class along with two derived classes, Savings and Current. Problem Statement# Write a code that has: ● A parent class named Account. ○ Inside it define: ■ a protected double member balance ■ public void Withdraw(double amount) ■ public void Deposit(double amount) ■ public void printBalance() ● Then, there are two derived classes ○ Savings class ■ has a private member interestRate set to 0.8 ■ Withdraw(double amount) deducts amount from balance with interestRate ■ Deposit(double amount) adds amount in balance with interestRate ■ printBalance() displays the balance in the account ○ Current class ■ Withdraw(double amount) deducts amount from balance ■ Deposit(double amount) adds amount in balance ■ printBalance() displays the balance in the account Input# ● In the Savings class, balance is set to 50000 in the parametrized constructor ● In the Current class, balance is set to 50000 in the parametrized constructor Output# Balance before…
build a student class implement the student class with the following instance variables: * id * firstName *lastName *dateOfBirth * Major create an __init__ function adn initialize all the fields make the "major" an option field and set a default value to "undefined" create a setter and getter function for all these five variables create another function: "print_student_info()" which prints 5 pieces of information: id, first name, last name, date of birth, and major. Make sure to have proper formatting done for printing these 5 things. Use the student class Task 1: create an empty list named "all_students" Task 2: create a variable named "id" and initialize it to 100 (some default value to start with, next id would be 101) Task 3: ask the user for input "How many students:" Task 4: Now run a for loop based on that input number and do the following things for each iteration: - get input of student's first name, last name, date of birth, and major - user should be able to skip the…

Define the Student class that has two attributes: name and gpa Implement the following instance methods: A constructor that sets name to "Defualt name"(What ever you want to give) and gpa to 1.0 set_name(self, name) - set student's name to parameter name get_name(self) - return student's name set_gpa(self, gpa) - set student's gpa to parameter gpa get_gpa(self) - return student's gpa Ex. If a new Student object is created, the default output is: Default name/1.0 Ex. If the student's name is set to "Frank" and the gpa is set to 3.7, the output becomes: Frank/3.7
Step 1: Extend the ItemToPurchase class per the following specifications: Private fields string itemDescription - Initialized in default constructor to "none" Parameterized constructor to assign item name, item description, item price, and item quantity. Public member methods setDescription() mutator & getDescription() accessor printItemCost() - Outputs the item name followed by the quantity, price, and subtotal printItemDescription() - Outputs the item name and description Ex. of PrintItemCost() output: Bottled Water 10 @ $1 = $10 Ex. of PrintItemDescription() output: Bottled Water: Deer Park, 12 oz.

(Java) Question 5,6 ANSWER BOTH PART 1 AND 2!!! Explain the answer step-by-step and include verbal explanation. Thank you! Given the below Car class, update the default constructor so that it calls the two argument constructor. public class Car { private String make;private String model;public Car() {make = "Make unknown";model = "Model unknown";}public Car(String make, String model) {this.make = make;this.model = model;} public String getMake() {return make;}public String getModel() {return model;}public void setMake(String make) {this.make = make;}public void setModel(String model) {this.model = model;}public boolean timeForService(int currMileage) {if (currMileage < 10000) {return true;}return false;}@Override public String toString() {return "Make: " + make + "\nModel: " + model;}} PART 2 Next, override the equals() method for the above Car class using the formula provided in class.
Consider a class BankAccount that has • Two attributes i.e. accountID and balance and• A function named balanceInquiry() to get information about the current amount in the account Derive two classes from the BankAccount class i.e. CurrentAccount and the SavingsAccount. Both classes (CurrentAccount and SavingsAccount) inherit all attributes/behaviors from the BankAccount class. In addition, followings are required to be the part of both classes• Appropriate constructors to initialize data fields of base class• A function named amountWithdrawn(amount) to withdraw certain amount while taken into account the following conditionso While withdrawing from current account, the minimum balance should not decrease Rs. 5000o While withdrawing from savings account, the minimum balance should not decrease Rs. 10,000• amountDeposit(amount) to deposit amount in the accountIn the main() function, create instances of derived classes (i.e. CurrentAccount and SavingsAccount) and invoke their respective…
