Thread: Payroll assignment

Hi guys, I'm having some issues with this format specifier error, but I can't find the error. When I input integers, the code runs fine.
In addition, when I input a number greater than 40 for the hours, it gets an error too .

So I'm getting errors for when I input:
[*]decimal values for either: hourly pay rate or hours worked
and[*]if I input a number > 40 for the hours variable, it returns an error.

PLEASE CLICK SPOILER below for the error:
[spoiler]run-single:
Enter hourly rate in dollars and cents --> 8
Enter number of hours and tenths worked --> 45

PAYROLL REPORT
Rate: 8.00
Hours: 45.00

So I'm getting errors for when I input:[*]decimal values for either: hourly pay rate or hours worked
and[*]if I input a number > 40 for the hours variable, it returns an error.

the error you encounter is because of this line:
System.out.printf ("Gross Pay: %32.2f \n", grossPay
+ "includes overtime");

when the hours > 40
it will execute the following statement in your code

if (hours > 40)
            { 
                overtime = true;
                grossPay = rate * 40 + (hours - 40) * (rate * 1.5);
                System.out.printf ("Gross Pay: %32.2f \n", grossPay   
                + "includes overtime");
            }

but the way you used System.out.printf is invalid.
if you want to concatenate "includes overtime" after grosspay
it should be like this
System.out.printf ("Gross Pay: %32.2f \n", grossPay);
System.out.println(" includes overtime");
(not sure if can do it in a single liner code)

but if you the output to be 1 line like: Gross pay 123123 includes overtime
try to used String.format

you format gross pay wint %32.2f, i think it will also work with this %.2f .2f means to format decimal in 2 decimals places only
