Expand the Employee Payroll program to include hourly based and salary based emp

Question

Expand the Employee Payroll program to include hourly based and salary based employees. This phase uses an array of employee objects, inheritance for different classes of employees, and polymorphism for salary computation. The 52 week yearly salary as well as number of overtime hours worked by a salary based employee is given). For salary based employees, to find the regular (gross) pay for a week, divide the salary by 52. To compute the overtime pay for a salary based employee, first find the hourly rate by dividing the gross pay by 40, and then compute overtime pay. For every employee, overtime pay, tax amount, and net pay must also be computed. In addition, the program should find the minimum and maximum net pay of all employees as well as sort the employees based on their net pay (ascending order).

using code I am still getting errors in DEVC++, also what should be in my salraiedemployeed.in file

Explanation / Answer

import java.util.Scanner;
class payroll {
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.println("Enter employee's name:");
String employee = input.next();
System.out.println("Enter number of hours worked:");
double hours = input.nextDouble();
System.out.println("Enter hourly pay rate:");
double pay = input.nextDouble();
double gross_pay = pay * hours;
System.out.println("Enter federal tax withholding rate:");
double fedtax = input.nextDouble();
double fedtaxr = fedtax * 0.20;
System.out.println("Enter state tax withholding rate:");
double statetax = input.nextDouble();
double statetaxr = statetax * 0.20;
double deductions = fedtaxr + statetaxr;
double total_pay = gross_pay - deductions;
System.out.println("Employee name: " + employee);
System.out.println("Hours worked: " + hours);
System.out.println(" Enter payrate: " + pay);
System.out.println(" Enter gross pay: " + gross_pay);
System.out.println(" Deductions: ");
System.out.println(" Federdal Withholding (20.0%): " + fedtaxr);
System.out.println(" State Withholding (9.0%)" + statetaxr);
System.out.println(" Total deductions:" + deductions);
System.out.println("Total pay: " + total_pay);
}
}
