- 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…a) Given the following code segments: class MyClass { String name; double value; MyClass (String n, double v) { name = n; value =v; } String getName () { return name; } double getValue () { return value; } } (i) Explain what is immutable object.1 Class definition Define a class bankAccount to implement the basic properties of a bank account. An object of this class should store the following data: Account holder’s name (string) Account number (int) Account type (string, check/savings/business) Balance (double) Interest rate (double) – store interest rate as a decimal number. Add appropriate member functions to manipulate an object. Use a static member in the class to automatically assign account numbers. 2 Implement all appropriate member functions of a class. 3 write a program that illustrate how to use your class. Your program should have the following: Declare an array of 20 components of type bankAccount to process up to 20 customers. void menu() – helps the user to select if the customer is new or if they already exist. Furthermore, it prints the customer’s data or exits the program. Use a switch statement which uses the value from menu() as an expression to call the following user-defined functions: void…
