Enum example

Enum example

“LNSL” is a construction company. It pays daily wages to its workers. If a worker works (on weekdays) for 8hours then payment will be made per the agreed/standard rate. If the worker works for more than 8 hours then the extra hours worked will be paid at 1.5 times the agreed rate. During weekends, the rate will be 1.5 times the standard rate.

Note : to do this example use “enum”.

Solution:

package com.spaneos.core;

enum PayrollDay{

MONDAY(PayType.WEEKDAY),TUESDAY(PayType.WEEKDAY),

WEDNESDAY(PayType.WEEKDAY),THURSDAY(PayType.WEEKDAY),

FRIDAY(PayType.WEEKDAY),SATURDAY(PayType.WEEKEND),

SUNDAY(PayType.WEEKEND);

  private final PayType payType;

  PayrollDay(PayType payType){

         this.payType=payType;

  }

  double pay(double hoursWorked,double payRate){

         return payType.pay(hoursWorked,payRate);

  }

  private enum PayType{

   WEEKDAY{

    double overtimePay(double hrs,double payRate) {

           return hrs<=HOURS_PER_SHIFT?0:hrs-                                                            HOURS_PER_SHIFT)*payRate/2;

          }

    },

    WEEKEND{

            double overtimePay(double hrs,double payRate){

                    return hrs*payRate/2;

            }

    };

               

    private static final int HOURS_PER_SHIFT=8;

        abstract double overtimePay(double hrs,double payRate);

        double pay(double hrsworked,double payRate){

                   double basePay=hrsworked*payRate;

                      return basePay+overtimePay(hrsworked, payRate);

        }

     }

}

public class PaymentManager {

     public static void main(String[] args) {

                double amount=PayrollDay.SUNDAY.pay(5, 20);

                System.out.println(amount);

     }

}
