This looks like a homework problem. I'm willing to help but not unless you get going and show me some code.

Well here is a stub. You just need to code the first method according to the instructions above.

public class PayrollFile {  public void writeToFile(PaidEmployee){    //code goes here  }    void searchFile(PaidEmployee){    //code goes here  }    void outputFile(){    //code goes here  }}

So this should give you a pretty good start. I'll leave all the specifics for you to google for. This is a fairly simple exercise. Ask questions if you're stuck.

I Apologize for the late reply.  The Assignment is pretty much finished. Thank you all for your replies as they did actually prove helpful. Just for curiosity's sake as I have already handed it in, do you have any idea how you would solve the following problem?

 

The user input for employee ID must only be accepted if it is the letter E followed by 4 digits. Use the Java API to view the methods in the String class and/or Character class for appropriate methods that could assist you in validating the user input for employee ID.

 

 

This is part of the code i came up with but I can't find the appropriate if statement for employeeID

 

 

 

System.out.print("Please enter Employee ID: ");

employeeID = input.next();

if (employeeID //I need help here )

{

System.out.print("Employee ID must start with E and be followed by 4 digits");

}

 

System.out.print("Please enter First Name: ");

firstName = input.next();

 

System.out.print("Please enter Last Name: ");

lastname = input.next();

 

System.out.print("Please enter Pay Category: ");

paycategory = input.nextInt();

if (paycategory < 1 || paycategory > 4)

{

System.out.print("Input for pay category must be 1,2,3,4");

}

 

System.out.print("Please enter Hours Worked: ");

hoursworked = input.nextDouble();

if (hoursworked < 1 || hoursworked > 80)

{

System.out.print("Input for hours worked must be between 1 and 80 ");

}

 

PaidEmployee s1 = new PaidEmployee(employeeID, firstName, lastname, hoursworked, paycategory);

PayrollFile p1 = new PayrollFile ();

p1.writeToFile();

Yeah. Sure.

 

Anyway, you can use a combination of charAt and isDigit or you can use regular expressions (which will be a little more complicated).
