Design a class named Employee. The class should keep the following information infields:• Employee name• Employee number in the format XXX-L, where each X is a digit within the range0-9 and the Lis aletter within the range A-M.• Hire date* Write one or more constructors and the appropriate accessor and mutator methods for theclass.Next, write a class named ProductionWorker that extends the Employee class. TheProductionWorker class should have fields to hold the following information:• Shift (an integer)• Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift field will be an integer valuerepresenting the shift that the employee works. The day shift is shift 1 and the night shift isshift 2. Write one or more constructors and the appropriate accessor and mutator methodsfor the class. Demonstrate the classes by writing a program that uses a ProductionWorkerobject. have to use beginner code because this is an intro class.

A class called Author is designed to model a book's author. It contains:• Three private instance variables: name (String), email (String), and gender (char of either'm' or 'f');• An __init__() to initialize the name, email and gender with the given values• Getters/Setters: getName(), getEmail(), setEmail(), and getGender()(There are no setters for name and gender, as these attributes cannot be changed.)• A __str__() method that returns printable string of that object with the following format:"Author[name=?,email=?,gender=?]"e.g., "Author[name=Tan Ah Teck,email=ahTeck@somewhere.com,gender=m]".Write the Author class. Also write a test driver code to test all the public functions, e.g.,ahTeck = Author("Tan Ah Teck", "ahteck@nowhere.com", 'm') # Test the constructorprint(ahTeck) # Test __str__()ahTeck.setEmail("paulTan@nowhere.com") # Test setterprint("Name is: ", ahTeck.getName()) # Test getterprint("Email is: ", ahTeck.getEmail()) # Test getterprint("Gender is: ", ahTeck.getGender()) #…
