    Question Someone who can help me with my PAYROLL PROGRAM

    Greetings ,

    I have a problem with my payroll program .my problem is, how can I add error messages in my program.For example , if the user commit error 3 times quit the program after the 3rd message ,,another example,i need to ask a user to input his/her name in STRING only , if he/she input a number the program will ask to input again , another problem, user will input for no. of hours work should be numeric , if the input is character show the error message, then ask again to enter the no. of hours. In every error that the user might be committed give her/ her with appropriate message .

    here's my code .. this program is payroll for monthly salary .

    import java.text.DecimalFormat;
    import java.util.Scanner;
     
    public class EmployeePayroll {
     
     
        public static void main(String[] args) {

            int choice = 0;
            String again;

    Default Re: Someone who can help me with my PAYROLL PROGRAM

    Start with an error counter = 0, say numberOfErrors = 0, and check each user entry. If the user's entry is an error, the increment the error counter. Then check if the error counter > 3 and if so, let the user know they've errored out and exit.

    This approach requires the use of methods which you don't seem too familiar with. If you were, you wouldn't be repeating the same code over and over and over and over and . . . over again in what you posted.

    As for only accepting String inputs, since all alphanumeric inputs can be String objects, I assume you mean only allowing alpha characters. You can build your own character checker, you could use a regular expression, and there are probably a dozen other possible approaches.
