missing return statemnet error

[sammyboy78]

I'm trying to create a class "WeeklyPay" that contains the methods that class "WeeklyPayTest" will use to compute the weekly pay of an employee when the user inputs employee name, hours worked, and pay rate.
I get an error when trying to compile WeeklyPay.java:

WeeklyPay.java:78: missing return statement
}//end displayPay
^

Also if anyone sees anything else that's going to give me a problem please tell me about it. Thanks!

here is my code for WeeklyPay.java:

here is my code for WeeklyPay.java:

        System.out.println();
        input.nextLine();
 
    }//end displayPay
 

You declare the return type of that method as a String; nowhere in that little
method do you return a String; that's why the compiler is whining at you.

Your displayPay method signature says that it returns a String but it does not do that. The compiler therefore has to complain.

ok I changed that return type to void and it compiled along with my WEeklyPayTest.java. Now when I try to run the WeeklyPayTest I get this error:

Please enter employee name, enter stop to quit:

In your employeeName() method your create a local String empName; that one
will be set and your member variable with the same name will still remain null.

Thanks!

Now my problem is that when I run WeeklyPayTest it won't calculate my hours and rate. It keeps returning $0.00 no matter what amounts I enter:

C:\Documents and Settings\Sam>java WeeklyPayTest

Please enter employee name, enter stop to quit: Sam

Enter hours worked by Sam : 45

Enter rate of pay for Sam :$45

Employee name: Sam
Weekly pay amount: $0.00

Please enter employee name, enter stop to quit: stop

What do I need to do to get it to work like I need it to?

I never see your setPay() method being called anywhere in your code. That
method calculates the amount of money to be paid. Or maybe I'm just blind ;-)

sweet! I overlooked that. Now it works perfectly! Thanks for helping this java newbie out. I appreciate it.

Thanks; no problem; we're nice folks here actually as long as one shows that
s/he's been trying to solve some problem(s) him/herself first.If one gets stuck
then we'll help you out. OTOH if one is just too lazy to put some effort in at first,
we (read: I) are/am too lazy too to do any homework for others at all ;-)

You showed that you've put in a lot of work in it yourself so we'll help you out.
Have fun studying the Java programming language.


kind regards,

Jos
