Part (1) Define a class with the following specification: a. Create a class called Employee that has four instance variables - a (String) first name, a (double) payRate, a (double) normalHours, and a (double) extraHours. b. Make the instance variable payRate private and provide a mutator method (set) and an accessor method (get) to access this variable. In set method, if the supplied pay rate (parameter) is negative print an invalid message and do not change the instance variable payRate. A method calcPay() to calculate the employee pay by multiplying payRate by normalHours added to it the pay for extraHours. For every extra hour the pay rate is doubled. This method must return the pay as a result. d. A method print() that displays the normal and extra working hours and the calculated pay amount formatted to two decimal places as shown below. C.

Consider the above scenario, where Billing class has composition relationship with Doctor having private instance variables (docName, docID and docFee) and a public getDocID() method, Patient having private instance variables (pName, pID, pDisease), Medicine having private instance variables (medID, medName, medQty, medPrice), and MedicalTest having private instance variables (testID, testName, testPrice). In addition, each class shall have toString method to display its object state. Also define getDocInfo method in Billing class that shall return the doctor. Implement getPaymentAmount() method in Billing class that shall return the total billing amount that includes doctor fee, medicine cost and medical tests fee. Considering the above scenario, write code that shall perform the following in the driver/test class: Get an amount from user. Traverse the ArrayList<Billing> using enhanced for loop. Print the billing details of those bills having total billing amount greater or…
Q2: Consider the following statements: public class YClass { private int a; private int b; public void one() { } public void two(int x, int y); { } public YClass() { } } class XClass extends YClass { private int z; public void one() { } public XClass() { } } YClass yObject; XClass xObject; Write the definition of the default constructor of YClass so that the instance variables of YClass are initialized to 0. Write the definition of the default constructor of XClass so that the instance variables of XClass are initialized to 0. Write the definition of the method two of YClass so that the instance variable a is initialized to the value of the first parameter of two and the instance variable b is initialized to the value of the second parameter of two. please I want solution :(
Problem B Now we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…
Create a program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p)

Consider the following program which contains a class definition currently missing one line of code: class Pokemon: def __init__(self, pokemon_name): ██████ pikachu_name = 'Pikachu' pikachu = Pokemon(pikachu_name) print(pikachu.name) Suppose that we want the constructor of this class to initially set the value of the instance variable name based on its arguments. This implies that the expected output of the program is 'Pikachu'. What should the missing line of code be? a. name = pokemon_name b. name = pikachu_name c. pikachu.name = pikachu_name d. self.name = pokemon_name e. pikachu.name = pokemon_name f. self.name = pikachu_name

This chapter uses the class rectangleType to illustrate how to overload the operators +, *, ==, !=, >>, and <<. In this exercise, first redefine the class rectangleType by declaring the instance variables as protected and then overload additional operators as defined in parts 1 to 3. Overload the pre- and post-increment and decrement operators to increment and decrement, respectively, the length and width of a rectangle by one unit. (Note that after decrementing the length and width, they must be positive.) Overload the binary operator – to subtract the dimensions of one rectangle from the corresponding dimensions of another rectangle. If the resulting dimensions are not positive, output an appropriate message and do not perform the operation. The operators == and != are overloaded by considering the lengths and widths of rectangles. Redefine the functions to overload the relational operator by considering the areas of rectangles as follows: Two rectangles are the…
Consider a base class named Employee and its derived classes HourlyEmployee and PermanentEmployee while taking into account the following criteria.• Employee class has two data fields i.e. a name (of type string) and specific empID (of type integer)• Both classes (HourlyEmployee and PermanentEmployee) have an attribute named hourlyIncome• Both classes (HourlyEmployee and PermanentEmployee) have three-argumentconstructor to initialize the hourlyIncome as well as data fields of the base class• Class HourlyEmployee has a function named calculate_the_hourly_income to calculate the income of an employee for the actual number of hours he or she worked. One hour income is Rs. 150 • Similarly, PermanentEmployee class has function named calculate_the_income to calculate the income of an employee that gets paid the salary for exact 240 hours, no matter how many actual hours he or she worked. Again, one hour salary is Rs. 150.Implement all class definitions with their respective constructors to…
