import java.text.*;

public class Arithmetic {

public static void main(String[] args) {
double price = getPrice();
int rating = rateWaiter();
double tipAmount = calculateTip(price, rating);
System.out.println("You should tip " + currencyFormatter(tipAmount)
+ " for a total of " + currencyFormatter(price + tipAmount));
}

public static int rateWaiter() {
Scanner keyboard = new Scanner(System.in);
int choice;
do {
System.out.print("Rate your waiter from 0-10: ");
choice = keyboard.nextInt();
} while (!(choice >= 0 && choice <= 10));
return choice;
}

public static String currencyFormatter(double amount) {
DecimalFormat myFormatter = new DecimalFormat("$###,###.00");
return myFormatter.format(amount);
}

System.out.print("Enter bill amount: ");

}
