public class Code_23 {
public static void main(String[] args) {
String employeeName;
double hoursWorked,hourlyPayRate,federalTaxRate,stateTaxRate;
Scanner input = new Scanner(System.in);
System.out.print("Enter employee's name: ");
employeeName = input.nextLine();
System.out.print("Enter number of hours worked in a week: ");
hoursWorked = input.nextDouble();
System.out.print("Enter hourly pay rate: ");
hourlyPayRate = input.nextDouble();
System.out.print("Enter federal tax withholding rate: ");
federalTaxRate = input.nextDouble();
System.out.print("Enter state tax withholding rate: ");
stateTaxRate = input.nextDouble();
System.out.printf("Employee Name: %s\n", employeeName);
System.out.printf("Hours Worked: %.1f\n", hoursWorked);
System.out.printf("Pay Rate: %.2f\n", hourlyPayRate);
System.out.printf("Gross Pay: %.2f\n", hoursWorked * hourlyPayRate);
System.out.printf("Deductions:\n");

System.out.printf(" State Withholding (%.1f%%): $%.2f\n", stateTaxRate * 100, stateTaxRate * hoursWorked * hourlyPayRate);
System.out.printf(" Total Deduction: $%.2f\n", federalTaxRate * hoursWorked * hourlyPayRate
+ stateTaxRate * hoursWorked * hourlyPayRate);
System.out.printf("Net pay: $%.2f\n", hoursWorked * hourlyPayRate
- federalTaxRate * hoursWorked * hourlyPayRate
