Thread: Simple Employee Payment Program

Hi all,

I am struggling with a small program which calculates an employee's payment due.

Some basic points:

* Min Wage as 6.21
* Hours over first 40 is payed at 1.5
* Program should output the payment due

As you can see below i am using if statements to try and do this.

I have looked through several times but cant work out where the problem is.

package latesttasks;
 
import java.util.*;
 
// Write a program that reads two numbers from the command line, the number of
// hours worked by an employee and their base pay rate. Then output the
// total pay due. Ensure the base pay rate entered is over minimum wage, if it 
// doesnt meet minimum wage print a warning and ask again for correct wage.
// After 40 hour mark, pay rate is 150% or i.e. * 1.5. 
public class Task2 {
 
    public static void main(String[] args) {
 
        Scanner scan = new Scanner(System.in);
 
        double hoursWorked;
        double minimumWage = 6.21;
        double baseRate;
        double overtimeRate;
        double amountDue;
        int hoursLimit = 40;
 
        System.out.println("Please enter your basic hourly rate: ");
        baseRate = scan.nextInt();
 
        if (baseRate < minimumWage) {
            System.out.println("Warning! rate doesn't meet minimum wage.");
            System.out.println("");
        }
        System.out.println("How many hours have you worked this week: ");
        hoursWorked = scan.nextInt();
        System.out.println("");
        if (hoursWorked <= 0) {
            System.out.println("You are due no payment.");
        } else if (hoursWorked > hoursLimit) {
            overtimeRate = baseRate * 1.5;
            amountDue = (baseRate * hoursLimit) + 
                    ((hoursWorked - hoursLimit) * overtimeRate);
            System.out.println(amountDue);
        }
        else {
            amountDue = (hoursWorked * baseRate);
            System.out.println(amountDue);
        }
    }
}

Any advice and suggestions appreciated.

How exactly is your program misbehaving?

hello djl1990
can you please specify the problem you're having ?
is it a calculation problem or a code problem?
which part of the code do you have problem with ?

I just did a modification on a little part of the code, hope it's correct !

import java.util.*;
 
// Write a program that reads two numbers from the command line, the number of
// hours worked by an employee and their base pay rate. Then output the
// total pay due. Ensure the base pay rate entered is over minimum wage, if it
// doesnt meet minimum wage print a warning and ask again for correct wage.
// After 40 hour mark, pay rate is 150% or i.e. * 1.5.
public class Task2 {
 
    public static void main(String[] args) {
 
        Scanner scan = new Scanner(System.in);
 
        double hoursWorked;
        double minimumWage = 6.21;
        double baseRate;
        double overtimeRate;
        double amountDue;
        int hoursLimit = 40;
 
	while(true){// to go over this, until the input is > minimumWage.
                System.out.println("Please enter your basic hourly rate: ");//
        	baseRate = scan.nextInt();
	    	if (baseRate < minimumWage) {
	            System.out.println("Warning! rate doesn't meet minimum wage.");
	            System.out.println("");
	        }
	        else // if baseRate is > minimumWage, break the loop.
	        	break;
        }
 
        System.out.println("How many hours have you worked this week: ");
        hoursWorked = scan.nextInt();
        System.out.println("");
        if (hoursWorked <= 0) {
            System.out.println("You are due no payment.");
        } else if (hoursWorked > hoursLimit) {
            overtimeRate = baseRate * 1.5;
            amountDue = (baseRate * hoursLimit) +
                    ((hoursWorked - hoursLimit) * overtimeRate);
            System.out.println(amountDue);
        }
        else {
            amountDue = (hoursWorked * baseRate);
            System.out.println(amountDue);
        }
    }
}

Here was the error i was getting:

run:
Please enter your basic hourly rate:

--- Update ---

Thanks for the advice CosmicCode. I added the while true parts and break statement so now have this:

package latesttasks;
 
import java.util.*;
 
// Write a program that reads two numbers from the command line, the number of
// hours worked by an employee and their base pay rate. Then output the
// total pay due. Ensure the base pay rate entered is over minimum wage, if it 
// doesnt meet minimum wage print a warning and ask again for correct wage.
// After 40 hour mark, pay rate is 150% or i.e. * 1.5. 
public class Task2 {
 
    public static void main(String[] args) {
 
        Scanner scan = new Scanner(System.in);
 
        double hoursWorked;
        double minimumWage = 6.21;
        double baseRate;
        double overtimeRate;
        double amountDue;
        int hoursLimit = 40;
 
        while (true) {
            System.out.println("Please enter your basic hourly rate: ");
            baseRate = scan.nextInt();
 
            if (baseRate < minimumWage) {
                System.out.println("Warning! rate doesn't meet minimum wage.");
                System.out.println("");
            } else {
                break;
            }
        }
        System.out.println("How many hours have you worked this week: ");
        hoursWorked = scan.nextInt();
        System.out.println("");
        if (hoursWorked <= 0) {
            System.out.println("You are due no payment.");
        } else if (hoursWorked > hoursLimit) {
            overtimeRate = baseRate * 1.5;
            amountDue = (baseRate * hoursLimit)
                    + ((hoursWorked - hoursLimit) * overtimeRate);
            System.out.println(amountDue);
        } else {
            amountDue = (hoursWorked * baseRate);
            System.out.println(amountDue);
        }
    }
}

However i am getting the following:

run:
Please enter your basic hourly rate:
10.49

Now you specified it, thank you for that! .

the problem is this code : baseRate = scan.nextInt();

it takes the next integer value, but when you input a double value an error occurs.

so just change it to > baseRate = scan.nextDouble();

and this should work !

hope this helped !
