Explanation / Answer
This is the code you want: import java.util.Scanner; public class TelephoneBillAmount { private static float TAXRATE = 0.07f; private static float MINRATE = 0.05f; private static float FEES = 1.00f; public static void main(String[] args) { float customersBillAmount[] = new float[10]; int customersCount = 0; float compTotal = 0; int menuOption; Scanner kb = new Scanner(System.in); do { System.out.println("-----------------------------------------"); System.out.println("Customer Menu"); System.out.println("-----------------------------------------"); System.out.println(" 1) Enter customer information"); System.out.println(" 2) Print average bill information"); System.out.println(" 3) Exit"); System.out.print(" Choose an option: "); menuOption = kb.nextInt(); switch (menuOption) { case 1: System.out.println("-----------------------------------------"); System.out.println("New Customer Information"); System.out.println("-----------------------------------------"); kb.nextLine(); System.out.print("Customer Name: "); String custName = kb.nextLine(); System.out.print("Customer Email: "); String custEmail = kb.nextLine(); System.out.print("Min Used: "); int minUsed = kb.nextInt(); float billAmt = calculateTotalBill(minUsed); compTotal += billAmt; customersBillAmount[customersCount++] = billAmt; System.out.println(String.format("Total Bill Amount: %.2f ", billAmt)); break; case 2: System.out.println("-----------------------------------------"); System.out.println("Customers Statistics"); System.out.println("-----------------------------------------"); System.out.println(String.format("Total Customers Entered: %d", customersCount)); System.out.println(String.format("Total Bill Amount: %.2f", compTotal)); float avgBill = compTotal / (float) customersCount; System.out.println(String.format("Average Bill Amount: %.2f", avgBill)); break; } } while (menuOption != 3); } public static float calculateTotalBill(int minUsed) { float minAmt = minUsed * MINRATE; float taxAmt = minAmt * TAXRATE; float billAmt = minAmt + taxAmt + FEES; return billAmt; } }
