Array List

I am working on a bank account program. There is Bank.java, BankAccount.java, and BankTester.java. I am trying to finish up a deposit method in the Bank class but am running into problems when trying to change the current balance to the new one. Here is my code for the method:


//PART B: Deposit funds
public void deposit(int accountNumber, double amount)
{

BankAccount a = accounts.get(accountNumber);
double bal = a.getBalance();
bal = (bal + amount);
//How do I make bal the current balance for the account??
}:confused:

BankAccount a = accounts.get(accountNumber);
does get(int) return an instance of BankAccount? And what is "accounts"?... Actually why are you making a new instance of BankAccount at all? Just use the BankAccount that calls the method.
//How do I make bal the current balance for the account??
does the Account have a field for its balance? Then you could just do (this.)balanceField = amount + (this.)getBalance;
where amount is your parameter in the method. I just put (this.) so you know it belongs to the calling Object. Hope that helped.

First of all, when you post next time please use an appropriate title in your question. Here your title and the question not make sense.

If you want to call a method from a class of another what you have to do basically? Create an instance of it. Then call the method. If that methods returns anything you have to store it in a correct data type variable. Do you have a clear idea about that?
