I am missing headers on my methods somewhere. And my teacher informed me that I'm calling get methods and sending information to them, & that I should not send data to get methods. They should look like my getFinalBill() method... Can anyone help me out?!

?MAIN CLASS:

public static void main(String[] args) { String choice; //Set variable for loop that allows user to rerun

do { //Loop gets readings from customer System.out.println("Welcome to the City Power Bill Calculator!");

Scanner input = new Scanner(System.in);

System.out.print("Please enter your previous meter reading:"); double preread = input.nextDouble(); //Users first input

System.out.print("Please enter your current reading:"); double curread = input.nextDouble(); //Users second input Subclass MyUtility = new Subclass(curread, preread); //Access subclass System.out.printf("Your usage was %.1f KhWs ", MyUtility.getUsage(curread, preread)); //Call getusage

//Assign usage to the variable "total" to determine rate double total = MyUtility.getUsage(curread, preread);

System.out.printf("Your rate was $%.4f/KhWs ", MyUtility.getRate()); //Return rate

double rate = MyUtility.getRate(); //Assign rate to variable

System.out.printf("Your subtotal is $%.2f ", MyUtility.getSubtotal(total, rate)); //Call getsubtotal

double subtotal = MyUtility.getSubtotal(total, rate); //Assign subtotal double TAXPERCENT = MyUtility.getTaxper();

System.out.printf("Your tax was $%.2f ", MyUtility.getTax(subtotal, TAXPERCENT));//Call gettax double tax = MyUtility.getTax(subtotal, TAXPERCENT); //Assign tax double totalbill = (subtotal + tax); //Assign bill total

System.out.printf("Your total bill this month is $%.2f ", totalbill); //Return the over all bill amount

System.out.println("Would you like to run again? y or n"); choice = input.next(); //User can rerun program or not

} while (choice.equalsIgnoreCase("y")); //Reruns program

System.out.println("Thank you for " + "using the program! Goodbye"); //Ends program }//End Main Method }
