Question

This is my code but my overtime calculation is wrong and I cant figure out how to round to two decimal places import java.util.Scanner; public class HourlyWage { public static void main(String[] args) { //Variables double totalWage; double totalOvertimePay; double totalPay; String name; double overtimeHours = 0.0; double hoursWorked = 0.0; double hourlyWage = 0.0; Scanner keyboard = new Scanner(System.in); System.out.println("Please enter your name "); name = keyboard.next(); System.out.println("Please enter your hourly wage "); hourlyWage = keyboard.nextDouble(); System.out.println("How many hours have you worked in the past week"); hoursWorked = keyboard.nextInt(); if(hoursWorked > 40) { overtimeHours = hoursWorked - 40; totalOvertimePay = overtimeHours * ( hourlyWage * 1.5); System.out.print(totalOvertimePay); totalWage = hourlyWage * 40; System.out.print(totalWage); totalPay = totalOvertimePay + totalWage; System.out.printf("10%.2f\n", totalPay ); }else if(hoursWorked <= 40) { System.out.println("Your total pay is: " + "$" + hourlyWage * hoursWorked ); } }//close main }//close class

HI,

Please find changed code below.code changes are highlighted with output attached.

along with screenshots of calculator ouputs.

import java.util.Scanner;
import java.math.BigDecimal;
import java.math.RoundingMode;

public class Main
{
public static void main(String[] args)
{
//Variables
double totalWage;
double totalOvertimePay;
double totalPay;
String name;
double overtimeHours = 0.0;
double hoursWorked = 0.0;
double hourlyWage = 0.0;
  
Scanner keyboard = new Scanner(System.in);
System.out.println("Please enter your name ");
name = keyboard.next();
System.out.println("Please enter your hourly wage ");
hourlyWage = keyboard.nextDouble();
System.out.println("How many hours have you worked in the past week");
hoursWorked = keyboard.nextInt();
  
if(hoursWorked > 40)
{
overtimeHours = hoursWorked - 40;
totalOvertimePay = overtimeHours * ( hourlyWage * 1.5);
  
// Here I have used bigdecimal to round to 2 decimal plces with rounding mode as halp_up
// This is the easiest way to round floats and doubles in java.
// halp_up rounds the number towards nearest neighbour.
BigDecimal totalOvertimePaybd = new BigDecimal(totalOvertimePay).setScale(2, RoundingMode.HALF_UP);
System.out.println(totalOvertimePaybd.doubleValue());
  
totalWage = hourlyWage * 40;
BigDecimal totalWagebd = new BigDecimal(totalWage).setScale(2, RoundingMode.HALF_UP);
System.out.println(totalWagebd.doubleValue());
totalPay = totalOvertimePaybd.doubleValue() + totalWagebd.doubleValue();
System.out.printf("%.2f\n", totalPay ); // I am not sure why 10 was used in your code posted in question.
  
}else if(hoursWorked <= 40)
{

   // Big decimal can be used here also, if not just for overtime calculation
System.out.println("Your total pay is: " + "$" + hourlyWage * hoursWorked );
  
}
  
}//close main
}//close class

thanks.
