Question 1 Consider the following ULM class diagram: «abstract» Programmer #name: String #salary: double +Constructors() +annualPay(): double FullTime -overtimeHours: int +Constructors() +getters() & setters() +annualPay(): double 1- Create both classes considering that the FullTime is a child of the Programmer class. 2- Make sure you represent the class well in your code (use the same naming of attributes, classes and methods). 3- Override the annualPay() method so that it returns the value of 0 (zero) in the Programmer class and calculate the annual pay in the FullTime class based on the following formula: If overtime hours is 100 or less: Annual Pay = salary * 12 + overtime hours * 200 If overtime hours are more than 200: Annual Pay = salary * 12 + overtime hours * 300

Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.

Problem: Create the class on the UML class diagram. Account + balance: double + interest: double + owner: String +id:int + withdrawal(double amount): double + deposit(double amount): double + calculateNextAmount():double While creating your class: 1) Write the class according to the UML class digram. 2) Encapsulate balance,interest, owner and id values. 3) Create getter, setters for balance and interest. Not for id and customer. So, owner and id will only be obtained while creating the objects. 4) Create constructor for the class. In your main program: 5) Create 5 account objects. 6) Withdraw some amount of Money from the accounts and inform the user about the new amount. If there is no enough Money, user should be informed. (Make validation) 7) Deposit some amount of Money to the accounts. Inform the user about new amount. 8) Calculate new amount of Money for the accounts one year later and write to console.

True or False, An abstract class must have at least one abstract method.
Consider the following class declaration: class Thing {private: int x; int y;static int z; public:Thing(){ x = y = z; }static void putThing(int a) { z = a; }};int Thing:: z = 0:Assume a program containing the class declaration deﬁnes three Thing objects with the following statement:Thing one, two, three;A) How many separate instances of the x member exist?B) How many separate instances of the y member exist?C) How many separate instances of the z member exist?D) What value will be stored in the x and y members of each object?E) Write a statement that will call the putThing member function before the Thing objects are deﬁned.
QUESTION 16 What must be true of a class with one abstract method? O The class must also implement the Iterable interface Any derived class must implement the method The abstract method must have the static modifier O The method cannot specify a return value QUESTION 17 Suppose we wanted to design a set of classes for a veterinarian's office. Our Customer class looks like this: public class Customer { Pet [] pets; } Select all the statements that are true Once the size of the pets array has been set, it cannot be changed Because we're using an array, all pets must be the same A customer must have at least one pet We also need to declare a Pet class QUESTION 18 What is the proper use of an enumeration? To define a set of ordered values To enforce the use of the Comparable interface O To define, or enumerate, the values returned by a Random object generator O To define the classes in an inheritance hierarchy
Programming Language = Python 1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: • Employee name • Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • Shift number (an integer, such as 1, 2, or 3) • Hourly pay rate The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object and then use the object’s accessor methods to retrieve it and display it on the…

In-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract. Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0 Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: # Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: # Write a TestShape class that has the main method, which creates…
