//Java code

import java.text.NumberFormat;

public class Employee {
    private String firstName;
    private String lastName;
    private double hours;
    private double rate;

    //Overload constructor
    public Employee(String firstName, String lastName, double hours, double rate) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.hours = hours;
        this.rate = rate;
    }
    //Constructor
    public Employee()
    {

    }
    //getters and setters

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public double getHours() {
        return hours;
    }

    public void setHours(double hours) {
        this.hours = hours;
    }

    public double getRate() {
        return rate;
    }

    public void setRate(double rate) {
        this.rate = rate;
    }
    // Calculate pay of employee
    public double calPay() {
        double salary =0;
        if (hours <= 40)
        {
            salary = hours * rate;

        }
        else
        {
            salary = 40*rate + (hours-40)*rate*1.5;
        }
        return salary;
    }

    /**
     * 
     * @return Description of the employee object
     */
    @Override
    public String toString() {
        return String.format("%5s %20.20s %10.20s","Name: ",firstName+" "+lastName," Salary: "+ NumberFormat.getCurrencyInstance().format(calPay()));
    }
}

//=======================================

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class SalaryCalcLoop
{
    public static void main(String[] args) {
        //Create employee object
        Employee employee = new Employee();
        try {
            //Open file to read
            Scanner sc = new Scanner(new File("payroll.txt"));

            //Read the file until it has next line
            while (sc.hasNextLine())
            {
                //Set the attributes
                employee.setFirstName(sc.next());
                employee.setLastName(sc.next());
                employee.setHours(Double.parseDouble(sc.next()));
                employee.setRate(Double.parseDouble(sc.next()));
                //Print employee object with pay details
                System.out.println(employee);
            }
        } catch (FileNotFoundException e) {
            System.err.println("File not found!");
        }


    }
}

//File

//Output
