Counter not incrementing

Question

Here is the code from one of my classes, these methods are used when a button is cliked in another class.
My problem is that the counter for rate is not incrementing for some reason.
Can anyone see a reason from the code why?
public class AccountModel
    private Account c, d;
    private int counter=0;
    public AccountModel()
        c = new Account();
        d = new Account();
    public AccountModel(String Name1, int intialAge1, String Name2, int intialAge2)
        c = new Account();
        c.setName(Name1);
        c.setInitialAge(intialAge1);
        d = new Account();
        c.setName(Name2);
        c.setInitialAge(intialAge2);
    public void saveData(int option, String newName, double newDeposit, int newInitialAge,
                         double newRate)
            if (option==1)
                setData(c,newName,newDeposit,newInitialAge,newRate);
            else if (option==2)
                setData(d,newName,newDeposit,newInitialAge,newRate);
    public void setData(Account a, String name, double deposit, int initialAge, double rate)
                a.setName(name);
                a.setDeposit(deposit);
                a.setInitialAge(initialAge);
                a.setRate(rate);
    public String showData(int option)
        String display = "";  //display string to return
        Account acc;    //local account variable
        if(option==1)   acc=c;  //choose which account
        else acc=d;
        //build string
        display += "Name: " + acc.getName() + "\n";
        display += "Initial Age: " + acc.getInitialAge() + "\n";
        display += "Actual Age: " + acc.getActualAge() + "\n";
        display += "Total Balance: " + acc.getBalance() + "\n";
        display += "Total Deposit: " + acc.getTotalDeposit() + "\n";
        display += "Total Interest: " + acc.getTotalInterest() + "\n";
        display += "Total Withdrawals: " + acc.getTotalWithdrawal() + "\n";
        display += "Interest Rate: " + acc.getRate() + "\n";
        return display;
    public double getBalance(int option)
        Account acc;
        if(option==1) acc=c;
        else acc=d;
        double balance = acc.getBalance();
        double deposit = acc.getDeposit();
        double rate = acc.getRate();
        for (int i = 0; i < acc.getYears(); i++)
            balance = (balance + deposit*12) * (1 + rate/100);
            if (counter % 10==0)
                rate = rate + 0.01;
            counter++;
        acc.setBalance(balance);
        return balance;
    public double keepDepositing(int option, int continuedYears)
        Account acc;
        if(option==1) acc=c;
        else acc=d;
        double balance = acc.getBalance();
        double deposit = acc.getDeposit();
        double rate = acc.getRate();
        for (int i = 0; i < continuedYears; i++)
                balance = (balance + deposit*12) * (1 + rate/100);
                if (counter % 10==0)
                    rate = rate + 0.01;
                counter++;
        acc.setBalance(balance);
        return balance;
    public double startWithdrawing(int option, double withdrawals, int withdrawalYears)
        counter=0;
        Account acc;
        if(option==1) acc=c;
        else acc=d;
        double balance = acc.getBalance();
        double rate = acc.getRate();
        for (int i = 0; i < withdrawalYears; i++)
                balance = (balance - withdrawals*12)*(1 + rate/100);
        acc.setBalance(balance);
        return balance;
        }

Answer 1

rate is a local variable in all your class methods. When you leave the method the value goes out of scope.
You don't post your Account class, so I can't tell if it has a rate data member.
If you want it to persist after you've left those methods, make it a data member in the AccountModel class.
