hey pple, I have this banking program that I have build but it not running properly, somewhere along the codes, something is wrong, I dont what, I dont know if the calculation is wrong somewhere along the lilnes . I will post all of my classes so that you can get an idea what I am trying to say and I will also post the outcome when I run it and I will also explain it. what is supposed to be doing and it is not doing. so here goes. first one is the transaction account. after each class I will explain what each class supposed to do when it run
transaction account
this transaction account supposed to gave the amt of transaction, gave a new balance after this transaction and the description of the transaction and it is not doing that. it also should be ablto show the date of this transaction, the type of transaction such as "W", for withdrawal, "D' for deposit
second class is the saving account
this saving account supposed calculate the interest rate . and the constructor should initialize all of the parent variables. as well as my own.
next is the chequing account
this chequing account supposed to have an overdraft limit to which u can widthdraw more that you have and also override the widthdrawal and deposit methods that is to cater for the overdraft limit. also if the overdraft limit is 500, this means that once the balance is 0, the user has the ability to withdraw up to 500 however the balance should show up as -500,for e.g if the user deposit 300, the balance is -200 and to which it is not doing
next is the customer class
this class should stored all of the information of the customer.
up next is the account class
the acct class should be able to stored the transaction on the account stored in arraylist, withdraw and deposit methods to withdraw and deposit funds.
and this is my main
for e.g if the user clicked on the 'o' to open an account ( it keep loopin) here is the outcome
it keep looping
when u click on "d" to deposit, the outcome is this
