    Why did you delete the code?
    For anyone interested, here is the code:
    import javax.swing.JOptionPane;
     
    public class CellPhoneBill 
    {
     
        public static int accountNum, dayMinutes, nightMinutes, totalMinutes,
            acctCall;
        public static char serviceCode, serviceCall;
        public static double amountDue;
        public static String outputStr, acctStr, serviceStr;
     
        public static void main(String[] args) 
        {
            getAccountNum(accountNum);
            getServiceCode(serviceCode);
            serviceSwitch(serviceCode);
            System.exit(0);
        }
     
        public static double calculateRegBill(int a) 
        {
            amountDue = 10;
            if (a > 50)
            amountDue = 10 + (a - 50) * .2;
            return amountDue;
        }
     
        public static double calculatePremBill(int a, int b) 
        {
            double dayCost = 0, nightCost = 0;
            if (a > 75)
                dayCost = (a - 75) * .1;
            if (b > 100)
                nightCost = (b - 100) * .05;
            amountDue = 25 + (nightCost + dayCost);
            return amountDue;    
        }
     
        public static int getAccountNum(int a) 
        {
            a = Integer.parseInt(JOptionPane.showInputDialog("Enter account number"));
            accountNum = a;
            return accountNum;
        }
     
        public static char getServiceCode(char b) 
        {
            b = JOptionPane.showInputDialog("Enter service code").charAt(0);
            serviceCode = b;
            return serviceCode;
        }
     
        public static void serviceSwitch(char a) 
        {
            switch (a) 
            {
            case 'r':
                case 'R':
                    amountDue = calculateRegBill(Integer.parseInt(JOptionPane.showInputDialog("Enter amount of " +
                    " minutes used in billing period")));
                    outputStr = "Account Num: " + accountNum + "\n Account Type" +
                    ": Regular" + "\nAccount Minutes Used: " + totalMinutes + "\nAmount Due: $" + String.format("%.2f", amountDue);
                    JOptionPane.showMessageDialog(null, outputStr, "Account" +
                    " Information", JOptionPane.INFORMATION_MESSAGE);
                    break;
                    case 'p':
                      case 'P':
                          dayMinutes = Integer.parseInt(JOptionPane.showInputDialog("Enter amount" +
                      "of minutes used between 6:00 a.m. to 6:00 p.m."));
                          nightMinutes = Integer.parseInt(JOptionPane.showInputDialog("Enter amount" +
                      "of minutes used between 6:00 p.m. to 6:00 a.m."));
                          amountDue = calculatePremBill(dayMinutes, nightMinutes);
                          outputStr = "Account Num: " + accountNum + "\n Account Type" + ": Premium" + 
                          "\nAccount Minutes Used: " + totalMinutes +
                          "\nAmount Due: $" + String.format("%.2f", amountDue);
                          JOptionPane.showMessageDialog(null, outputStr, "Account" +
                          " Information", JOptionPane.INFORMATION_MESSAGE);
                          break;
                          default:
                              JOptionPane.showMessageDialog(null, "Invalid Account type",
                                      "Account Information", JOptionPane.INFORMATION_MESSAGE);
                              }
            }
        }
