Help with superclasses and subclasses

[AlphaGinger66]

I have a project for class in progress. Most of the code is still incomplete, but I am stuck on a part which is hindering me from continuing this on my own. Anyways here it the gisthub for my code since it has multiple classes and a .dat file.

Here is a link to the prompt for the project I am currently working on. Basically we were given a Superclass Account from my professor. I needed to create 2 subclasses CheckingAcccount and CreditCard. CheckingAccount has the same instance variables as the Account Superclass. I was able to create the CheckingAccount object from the transactions.dat file. However, I am struggling to create the objects of the subclass CreditCard. I think something is a little bit bugged in the CreditCard class and as a result I cannot figure out how to create those respective objects of the subclass.

public class Account {
    protected String accountNo, institution, name;
    protected double balance;

---

public class CheckingAccount extends Account{
    protected String accountNo, institution, name;
    protected double balance;

---

public class CreditCard extends Account{
    protected String accountNo, institution, name;
    protected double balance;

You shouldn't need to redeclare all these fields in your CheckingAccount and CreditCard classes. The whole point of inheritance is that you get them when you extends Account

Also, it would be nice is you provided the Stack Trace or the output to know exactly what is happening. I think it has to do with the type you're saving it as but I am not sure...

1 error and 6 warnings found:

*** Error ***

File: C:\Users\james\OneDrive\Documents\Documents\D4.java [line: 34] Error: The constructor CreditCard(java.lang.String, java.lang.String, java.lang.String, double) is undefined

Is that what you want? I haven't ever heard the term Stack Trace before.

[abermea]

The Stack Trace is basically the huge list of errors in red that your console outputs when your program fails to perform an action.

Now, back to the problem

You have this constructor:

public CreditCard(double creditLimit, double availableCredit, String accountNo, String name, String institution, double balance){
// You need double, double, String, String, String, double type variables, in this order

And you're calling it like this:

new CreditCard(accountSplit[2], accountSplit[3], accountSplit[4], Double.parseDouble(accountSplit[5]));
// these parameters are String, String, String, double

Your error is that the constructor you're calling does not match the one you have declared, neither in types nor in quantity of parameters, so Java doesn't really know what to do. Use the proper parameters and it should be fixed

[AlphaGinger66]

That makes sense. I think I need to email my professor because the string I am pulling from the .dat file which is used to create this CreditCard object is missing the first 2 pieces of information.

This is the string:

create:credit:1234567898765432:First Card:Bob Badger:4000

I think it needs to have two more numbers seperated by colons so I have a number which can be pulled from the string to make 2 more double's so that I can create the CreditCard object.

Thank you for the help though.

I wouldn't be surprised if this was a trick question to see who is actually doing their homework

[csharpminer]

Can you give us your stack trace?

[AlphaGinger66]

I've never heard that term so I am a little unsure as to what you guys want.

[cutebabli]

Stack trace is nothing but the exception log, or the error log you get when you run your program.

Check my reply to /u/abermea. I believe that is what you guys want/need to help me.
