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…

Q2. Write a class Bank that has the following data members –Account Holder name (ah_name[]) –Account number (ac_number) •Must unique, system generates automatically, and must starting from 100 (Hints: Use another static variable and assign that variable to ac_number) –Balance in the account (ac_balance) •The class has the following member functions –A constructor to initialize the data members –Input() to takes name from the user –Deposit(parameter) to deposits balance in the account •Must accept parameter (The amount to deposit) –Withdraw(parameter) to withdraws balance after checking •Must accept parameter (The amount to withdraw) –Display() to show the name, account number, and balance
Create a class Student with following instance private variables and member functions: Variable: id (int), name (String), Major (String) Constructor: overloaded constructor Methods: Accessor/Mutator (Setter/Getters), toString Create class College with following instance variable and member function: Variable: SIZE (final and int), Student array example: Student[] student; Constructor: overloaded which take one input size and this will be the value of SIZE viable and Student array size. Methods: addStudent(id, name, major) method: This method will create and add student object to the student array and when the array gets full the method will give an error message saying that you cannot add more students searchStudent(id) method: This method uses sequential search algorithm to find a student using student id in the student array. If the student is found it will return the student object otherwise it will return null. Create class StudentSearch with the main method and the main method…
User-defined Class: You will design and implement your own data class. The class will store data that has been read as user input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named MoneyChange. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 6 instance variables to represent amounts for each of the 6 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide a legitimate justification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriate get and set methods for…

A class Person is given below as your base class. Your task is to create a class Employee which will contain objects of records for an employee and derived from the class Person. Guideline for an employee record: employee's name (which is inherited from the class Person) annual salary represented (type double) year the employee started work (type int) company ID number (type String) with a format of EMPXXX (where X are numbers) Create constructors and accessor methods which you think are needed for this program, as well as another method (print) to print out all the employee’s data once you call that method. Finally, create your TestEmployee class which will contain a main method to fully test your class definition. public class Person{ private String name; public Person(){ name = "No name yet."; } public Person(String n){ name = n; } public void setName(String newName){ name = newName; } public String getName(){ return name; } public void print(){…
Employee is a class with a function to set the details of the employee such as the emp_id, Name, Gender and city.The Fulltime Employee is a class derived from Employee has a function to set the Dearness Allowance (DA), House Rent Allowance (HRA) and EPF deduction. Part-time Employee is a class derived from Employee has a function to set the Shift (I,II, or III), Pickup Point, Pickup Time, Drop Point and Leaving Time.The Tech-Staff is a derived class from the Fulltime Employee class. The function set_basic() is to set the basic salary and Pay_Detail() is a function to display the Salary details.
3. Person and Customer Classes The Person and Customer Classes Write a class named Person with data attributes for a person’s name, address, and telephone number. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.
Define a Class Time with the following data members: hour, minute, and the following member functions: 1. Set_ data: that Stores parameters values into data members. 2. Update_time: that update the existing time by certain value (Add hours with hours and minutes with minutes). 3. Sum_time: that find the sum of given two times. 4. Ret_hm: that returns the hour and the minute of the time. Let your main function declare two objects, and print the values of the hour (h) and the minute (m) for the fastest time.

15. Suppose the class Employee is declared as follows: public class Employee { private String name; private double baseSalary: public void setName(String newName) {...} public void setBasSalary(double newSalary){...} public String getName() {...} public double getSalary({...} } a)Declare a class Manager that inherits from the class Employee and adds an instance variable bonus for storing a salary bonus. Omit constructors and methods. ANS: b) Which instance variables does the Manager class have? c) In the manager class, provide the method overrides the getSalary method from the class Employee so that it returns the sum of the salary and the bonus d) Based on the above question, which methods does the manager class inherit? e) In the manager class, override the getName method so that managers have a before their name (such as *John Smith).
