Rpay = hours * rate;
Opay = 0;
}

Rhr = 40;
Ohr = hours - Rhr;
Rpay = Rhr * rate;
Opay = Ohr * (1.5 * rate);

Scanner sc = new Scanner(System.in);
String name;
int shift = 0;
Double rate, hours;

name = sc.next();
System.out.println("Enter Your Shift, Enter 0 for Day, Enterv1 for Night");

shift=sc.nextInt();
System.out.println("Enter Number of Hours Worked");
hours = sc.nextDouble();
System.out.println("Enter Hourly Pay");
rate = sc.nextDouble();
SalaryCalc c = new SalaryCalc();
c.calPay(hours, rate);
Double Tpay = c.Rpay + c.Opay;
System.out.println();
System.out.println("Calculate Pay");
System.out.println("Employee Name: " + name);
System.out.println("Employee Regular Pay: " + c.Rpay);
System.out.println("Employee Overtime Pay: " + c.Opay);

ch=sc.next();

Note:

Update the input and output file file name in the below code

private static final String INPUT_FILE = "Payroll.txt"; 

// writes the calculated pay to the below file 
private static final String OUTPUT_FILE = "Payroll_Output.txt";

import java.io.*;
import java.util.Scanner;

public class SalaryCalculator {

    // read from the below file
    private static final String INPUT_FILE = "Payroll.txt";
    // writes the calculated pay to the below file
    private static final String OUTPUT_FILE = "Payroll_Output.txt";

    public static void main(String[] args) {


        try {
            Scanner fileReader = new Scanner(new File(INPUT_FILE));
            PrintWriter writer = new PrintWriter(new FileWriter(OUTPUT_FILE));

            while (fileReader.hasNext()) {
                String firstName = fileReader.nextLine();
                String lastName = fileReader.nextLine();
                int hours = Integer.parseInt(fileReader.nextLine());
                double rate = Double.parseDouble(fileReader.nextLine());

                double regularPay = regularPay(hours, rate);
                double overtimePay = overtimePay(hours, rate);

                writer.write(firstName + " " + lastName + "\r\n");
                writer.write("Regular Pay: $" + String.format("%.2f\r\n", regularPay));
                writer.write("Overtime Pay: $" + String.format("%.2f\r\n", overtimePay));
                writer.write("Total Pay: $" + String.format("%.2f\r\n", overtimePay + regularPay));
            }

            fileReader.close();
            writer.close();
        } catch (FileNotFoundException e) {
            System.out.println("Unable to read data from file: " + INPUT_FILE);
        } catch (IOException e) {
            System.out.println("Unable to write to file: " + OUTPUT_FILE);
        }
    }

    // takes in hours and rate returns the regular pay
    public static double regularPay(int hours, double rate) {
        if (hours <= 40) return hours * rate;
        else return 40 * rate;
    }

    // takes in hours and rate and returns the overtime pay
    public static double overtimePay(int hours, double rate) {
        if (hours <= 40) return 0;
        else return (hours - 40) * hours;
    }
}
