Depositing money into bank and then updating balance.HELP

Question

Hi,
Wondering if anyone could help me here. I'm codeing a bank program and one of the methods is depositing money into the account. now i can do that bit ok but i'm stuck when i want to update the display CORRECTLY afterwards.
Have a look see.
public class CurrentAccount
     private int accountNumber;
     private Student student1;
     private double interestRate;
     private int overdraft;
     private int initialAmount;
     private int withdrawAmount;
     private int depositAmount;
     private int balance;
     * Constructor for objects of class CurrentAccount
     public CurrentAccount(int accountNumber, Student newStudent, double interestRate, int overdraft, int initialAmount)
          this.accountNumber = accountNumber;
          student1 = newStudent;
          this.interestRate = interestRate;
          this.overdraft = overdraft;
          this.initialAmount = initialAmount;
I'M HAVING TROUBLE BELOW. I WANT THE 'RETURN BALANCE' METHOD TO RETURN THE UPDATED BALANCE AFTER I HAVE DEPOSITED MONEY INTO THE ACCOUNT. I CURRENTLY JUST HAVE IT SET TO RETURNING THE INITIAL AMOUNT.
     * This method returns the current balance in the account.
     public int getBalance()
     return initialAmount;
     * This method allows you deposit money in your account.
     public void despositAmount(int amount)
     if(amount > 0)
     balance = initialAmount + amount;
     System.out.println("Your current balance is:" + balance);
     else
     System.out.println("You must deposit a positive amount of money. eg. €10");
ANY HELP WOULD BE MUCH APPRECIATED! IF YOU NEED ANY MORE INFO OR IF I HAVEN'T MADE ANYTHING CLEAR THEN LET ME KNOW. CHEERS.

Answer 1

I'm now having trouble with this method.
If the amount attempting to be withdrawn is bigger than the balance then i want "You have insufficient funds" printed, this works ok. But then when i check the balance i get eg.-500 or whatever i attemped to withdraw. I just want the balance to be the same before i attempt to withdraw too big an amount. if you understand.
     * This method allows you to withdraw money from your account
     public void withdrawAmount(int amount)
     if(amount > 0)
     balance = balance - amount;
     System.out.println("You successfully withdrew: " + amount + " from your account");
     else
     System.out.println("You must withdraw a positive amount of money");
     if(amount > balance)
     balance = balance + amount - amount;
     System.out.println("You have insufficient funds");
     else
     balance = balance - amount;
     }
