Question

Write a Java Program using the concept of objects and classes. Make sure you have two files Employee.java and EmployeeRunner.java. Use the template below for ease. (Please provide detailed explanation)

Class Employee

Class Variables:

Name

Work hour per week

Hourly payment

Class Methods:

- Get/Sets

- generateAnnualSalary(int:Duration of employment)

           

  annual salary = Hourly payment * Work hours per week * 50

If the employee is working for more than 5 years,

10% added bonus

           

-void displayAnnualSalary ( )

before and after tax considering there’s an effective 25% tax

Class EmployeeRunner

main method

            - Create an object of type Employee

            - Prompt the user to insert name, work hour per week, hourly payment and duration of

                employment in years

• Generate annual salary and display the before and after tax amount

Answer 1

Java Program:

File: Employee.java

class Employee
{
   private String name;
   private int workHoursPerWeek;
   private double hourlyPayment;
  
   //Constructor
   public Employee()
   {
       name = "";
       workHoursPerWeek = 0;
       hourlyPayment = 0.0;
   }
  
   //Arg Constructor
   public Employee(String n, int hrs, double pay)
   {
       name = n;
       workHoursPerWeek = hrs;
       hourlyPayment = pay;
   }
  
   //Getter and Setter Methods
   public String getName()
   {
       return name;
   }
   public void setName(String n)
   {
       name = n;
   }
   public int getWorkHoursPerWeek()
   {
       return workHoursPerWeek;
   }
   public void setWorkHoursPerWeek(int hrs)
   {
       workHoursPerWeek = hrs;
   }
   public double getHourlyPayment()
   {
       return hourlyPayment;
   }
   public void setHourlyPayment(double pay)
   {
       hourlyPayment = pay;
   }
  
   //Method that generates Annual Salary
   public double generateAnnualSalary(int duration)
   {
       //Calculating annual salary
       double annualSal = (hourlyPayment * workHoursPerWeek * 50);
      
       //Checking duration
       if(duration > 5)
       {
           //Adding 10% Bonus
           annualSal = annualSal + (annualSal * 0.10);
       }
      
       return annualSal;
   }
  
   //Annual Salary Display
   public void displayAnnualSalary(double annualSal)
   {
       System.out.printf("\nBefore Tax: $%.2f \n", annualSal);
       //Adding tax
       double annualSalWithTax = annualSal + (annualSal*0.25);
       System.out.printf("\nAfter Tax: $%.2f \n", annualSalWithTax);
   }
}

File: EmployeeRunner.java

import java.util.*;

class EmployeeRunner
{
   //Main method
   public static void main(String[] args)
   {
       //Create an object of type Employee
       Employee empObj = new Employee();
      
       //Scanner object
       Scanner reader = new Scanner(System.in);
      
       //Prompting details from user
       System.out.print("Enter Student Name: ");
       String name = reader.nextLine();
       System.out.print("Enter work hour per week: ");
       int hrs = reader.nextInt();
       System.out.print("Enter hourly payment: $");
       double hourlyPay = reader.nextDouble();
       System.out.print("Enter duration of employment in years: ");
       int years = reader.nextInt();
      
       //Assigning values
       empObj.setName(name);
       empObj.setWorkHoursPerWeek(hrs);
       empObj.setHourlyPayment(hourlyPay);
      
       //Generating Annual Salary
       double annualSal = empObj.generateAnnualSalary(years);
      
       //Printing salary
       empObj.displayAnnualSalary(annualSal);
      
       //Closing reader
       reader.close();
   }
}
