JAVA PROGRAMING

1. Employee and productionWorker Classes Design a class named Employee.The class should keep folloqng information in fields. .Employee name .Employee number in the format XXX-L,where each X is a digit within the range 0-9 and the L is a letter within the range A-M .Hire date Write one or more constructors and the appropriate accessor and accesor and mutator methods for the class.Next, write a class named productionWorker that extends the Employee class.The productionWorker 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 value representing the shift that employee works. The day shift is shift i and the night shift is shift2. Write one or more constructor and the appropriate accessor and mutator methods for the class.Demonstrate the classes by writing a program that uses a productionWorker object.

2. In a particular factory,a shift supervisor is a salaried employee who supervises a shift.In addition to a salary,the shift supervisor earns a yearl bonus when his or her shift meets production goals.Design a ShiftSupervisor class that extends the Employee class you created in programming challenge 1. TheShiftSupervisor class should have a field that holds the annual salary and a field that holds the annual production bonus that a shift supervisor has earned.Write one or more constructor and the appropriate accessor and mutator methods for the class.Demonstrate the class by writing a program that uses a ShiftSupervisor object.

3. In a particular factory, a team leader is an hourly paid production worker that leads a small team. In addition to hourly pay, team leaders earn a fixed monthly bonus. Team leaders are required to attend a minimum number of hours of training per year. Design a Teamleader class that extends the productionWorker.The Team leader should have fields for the monthly bonus amount, the required numbers of training hours and the number of training hours the team leader has attended.Write one or more constructor and the appropriate accessor and mutator methods for the class. Demonstrate the class by writing a program that uses a TeamLeader Object.

4. Design a class named person with fields for holding a person's name,address,and telephone number.Write one or more constrctors and the appropriate mutator and accessor methods for the class's fields. Next,design a class named customer,which extends the person class.The customer class should have a field for a customer number and a boolean field indicating whether the customer wishes to be on a mailing list.Write one or more constructors and the appropriate mutator and accestor methods for the class's fields.Demonstrate an object of the customer class in a simple program.

5. A retail store has a preffered customer plan where customers can earn discounts on all their purchases. The amount of a customer's discount is determined by the amount of the customer's cumulative purchases in the store as follows: .When a preferred customer spends $500,he or she gets a 5 percent discount on all future purchases. .When a preffered customer spends $1,000,he or she gets a 6 percent discount on all future purchases .When a preffered customer spends $1,500,he or she gets a 7 percent discount on all future purchases .When a preffered customer spends $2,000 or more,he or she gets a 10 percent discount on all future purchases Design a class named PreferredCustomer,which extends the customer class you created in programing 4. The preferredCustomer class shoud have fields for the amount of the customer's purchases and the customer's discount level. Write one or more constructors and the appropriate mutator and accessor methods for the class's fields.Demonstrate the class in a simple program.
