    Default Subclass not compiling.

    Hi all. How's everybody doing? Good I hope. I'm hanging in there.

    What I have are some classes for a program I'm sure many of you have seen before, ye ol' BankAccount class. What I've done here is write a subclass that inherits from the the BA class. But the subclass doesn't compile and I can't figure out what to do. I keep getting the error below:

    SavingsAccount.java:10: error: no suitable constructor found for BankAccount(String,String)
    super(CName, CType);
    ^
    constructor BankAccount.BankAccount(int,String,String,String,d ouble,double) is not applicable
    (actual and formal argument lists differ in length)
    constructor BankAccount.BankAccount() is not applicable
    (actual and formal argument lists differ in length)
    1 error


    Below are the classes I've written. If anyone can point me in the right direction, it would be much appreciated.

    import java.util.*;  
    import java.io.*;  
    import java.text.DecimalFormat;
     
     
    class BankAccount 
    {

       String CustType;
    	private double Balance;
    	private double MonthlyFee;
     
    	private static int NumberOfBankAccounts = 0;
     
    	BankAccount() 
    	{
     
    		AccountNumber = 0;
    		AccountType = "";
    		CustName ="";

    ^
    The SavingAccount's super class: BankAccount does NOT have a constructor that takes two Strings as args.
    A couple of choices:
    Change the call to the super constructor to pass the args that it takes.
    Add a new constructor to the BankAccount class that takes two Strings as args
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks again Norm. (I was just moving this post to proper forum.) Anyway, you're fast. So, I had been thinking along the lines of your first suggestion, but does that mean I need to pass ALL the args of the BA class AND the two new ones I made? Can you do that?

    It means that the call to a constructor or a method MUST pass it the args that they require.

    Thanks for trying to help. But I'm sorry to say I'm just not getting it. I mean, I've passed it what it needs. Then I try passing all the args in the order that they appear in the super-class. Still a problem.

    --- Update ---

    Waaaaaiiiiit a minute, let me try something....

    Well, nevermind. I thought if I put all the args in the call to the super class that the super has, THAT would work. But alas...

    --- Update ---

    OK. Finally got it. Makes perfect sense now.

    public SavingsAccount(int AccNum, String AccType, String CName, String CType, double Bal, double mFee, double savNum, double savBal) //Not sure if CType is the arg needed.
    	{
    		super(AccNum, AccType, CName, CType, Bal, mFee);
    		savingsNumber = savNum;
    		savingsBalance = savBal;
    	}

    Sure thing Norm. Thanks for your help. You know, all those args just look wild to me. Logically I can see now why they are needed, but I just assumed there was a more 'succinct' way to do this.
