POMethod Retrieval and Inheritance Confusion

copied!<p>Ok,so I am getting a lot of trouble, I am still learning Java and my book has set me a task that I find common over the net, the part that I am stuck on is...</p> <p>I must create a bank account program, an account holder is given a savings account (which has an interest rate and no overdraft facility), and a checking account (which has an overfraft facility of £100 and no interest). </p> <p>I am not implementing the overdraft yet and am only half way to getting the withdraw and deposit function ready but my question is with the interest, I have defined in my superclass the savings account balance and the checking account balance so when working out my interest in the savings account class I cannot reference savebalance as I have made it private. I am trying to use the set.name method but i am clearly doing it wrong....</p> <p>A big smile and a thank you for any one who can help or give advice!</p> <p>Superclass is as follows:</p> <pre><code>public class BankDetails { private String customer; private String accountno; private double savebalance; private double checkbalance; //Constructor Methods public BankDetails(String customerIn, String accountnoIn, double savebalanceIn, double checkbalanceIn) { customer = customerIn; accountno = accountnoIn; savebalance = savebalanceIn; checkbalance = checkbalanceIn; } // Get name public String getcustomername() { return (customer); } // Get account number public String getaccountnumber() { return (accountno); } public double getcheckbalanceamount() { return (checkbalance); } public double getsavebalanceamount() { return (savebalance); } public void savewithdraw(double savewithdrawAmountIn) { savebalance = savebalance - savewithdrawAmountIn; } public void checkwithdraw(double checkwithdrawAmountIn) { checkbalance = checkbalance - checkwithdrawAmountIn; } public void savedeposit(double savedepositAmountIn) { savebalance = savebalance - savedepositAmountIn; } public void checkdeposit(double checkdepositAmountIn) { checkbalance = checkbalance - checkdepositAmountIn; } } // End Class BankDetails </code></pre> <p><strong>Sub Class is as follows:</strong></p> <pre><code> import java.util.*; public class Savings extends BankDetails { private String saveaccount; private double interest; public Savings(String customerIn, String accountnoIn, float interestIn, String saveaccountIn, double savebalanceIn) { super (customerIn, accountnoIn, savebalanceIn, interestIn); saveaccount = saveaccountIn; interest = interestIn; } public String getsaveaccountno() { return (saveaccount); } public double getinterestamount() { return (interest); } public void interestamount(String[] args) { BankDetails.getsavebalanceamount(savebalance); interest = (savebalance / 100) * 1.75; } } </code></pre>
