Write a class Account in Python that stores information about a bank account. (a) Your class should have at least three methods to manipulate any instance of the Account class: `withdraw()`, `deposit()`, and `__init__()`. (b) Your Account class should provide three class variables: - `interest_rate` set to 0.05 (5%) - `overdraft_limit` set to 500 (dollars), and - `overdraft_charge` set to 50 (dollars). These are values common to all accounts at this bank (i.e. all instances of this class). (c) Additionally, the Account class should create two instance variables: - `account_number` of the customer and - `balance` which is set to 0 dollars (it’s a new, empty account) These are values unique to each Account instance. (d) Allow your user to “overdraft” on their account. An overdraft occurs when money is withdrawn from a bank account and the available balance goes below zero. This allows a user to withdraw money on credit from the bank. The user should only be allowed to withdraw money up…

JAVA PROGRAMMING - Create a class named "Shape" that has rhe abstract methods getArea() and getPerimeter(). - Create a class named "Rectangle", "Square", and "Circle". Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. - For rectangle, create attribute length and width. For square, side. For circle, radius Inputs: 1. Char input for Shape Type (Rectangle, Square, Circle). 2. Dimensions for specific type of Shape Output: Shape: Rectangle Length: 10 Width: 50 Area: 500.00 Perimeter 120.00
This question concerns writing a Student class to model a student's name, composed of a first name, middle name and last name. The Student class should meet the following specification:Class StudentA Student object represents a student. A student has a first name, middle name and last name.Methodspublic void setNames(String first, String middle, String last)// Set the first, middle and last names of this Student object.public String getFullName()// Obtain the full name of this Student with the middle name converted to an initial only.2Thinking of the problem in terms of testing, there are three requirements that must be met:1. The setNames() method sets the names stored in the object i.e. the values of firstName, middleName, lastName.2. The getFullName() method obtains the name of the student with the middle name converted to an initial only.3. The getFullName() method does not change anything – i.e. it does not modify the values of firstName, middleName, lastNameHINT: To start your…
In Java, Write a line of code that performs each of the following tasks : (a) Call superclass Employee's toString method from subclass Pieceworker's toString method. (b)Specify that class Pieceworker inherits from class Employee. (c) Call superclass Employee's constructor from subclass Pieceworker's constructor - assume that the superclass constructor receives three strings representing the first name, last name and social security number.

Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.
Java - Polymorphism Create a class named “Shape” that has the abstract methods getArea() and getPerimeter(). Create classes named “Rectangle”, “Square”, and “Circle”. Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. For rectangle, create attribute length and width. For square, side. For circle, radius. Inputs 1. Char input for Shape type (R/S/C) 2. Dimensions of specific type of Shape C 5 Sample Output Shape(R/S/C): R Length: 10 Width: 50 Area: 500.00 Perimeter: 120.00
Modify the above code to use the alternative method for multithreading (i.e., implementing the Runnable interface). Name your main class RunnableHelloBye and your subsidiary classes Hello and Goodbye respectively. The fi rst should display the message ‘Hello!’ ten times (with a random delay of 0–2 s between consecutive displays), while the second should do the same with the message ‘Goodbye!’. Note that it will NOT be the main class that implements the Runnable interface, but each of the two subsidiary classes.
Create a class MyTime which has the datamembers as follows: 1. hour: integer (1 to 12)2. minute: integer (0 to 59)3. second: integer (0 to 59)4. pm: bool variable. True means PM time and false means AM time. Implement a default constructor, a parameterized constructor and a copy constructor. Write set and get functions for all the four members of the class. Overload these operators: 1. Extraction operator >> : Prompt the user for hours, minutes, seconds and for am/pm and initialize the structure. Left operand istream object and right operand MyTime2. Assignment = : Assign the right object to the left object. Both operands are of type MyTime.3. Insertion << : Print the time in the format HH:MM SS PM. Left operand of type ostream and right operand of type MyTime. this in c++.
