Passing method returned values between class

[Da1dmoney]

Is there a way to pass the value of a specific method from one class to another? For instance if i wanted to take the results of this:

 void withdraw(double amt){
balance = balance - amt;
 if (balance < 0) { 
sendWarning();
applyOverdraftFee();
}
}

And use it in another class like this:

 public String errorDescription(double balance, BankAccount toAccount)
	  {
 BankAccount method = new BankAccount(balance, acctNumber, acctNumber, acctNumber);
		this.toAccount = toAccount;
if(method.balance >0){ 				
return "ERR2556B - insufficient funds"; 			} 			
else 
return "ERR2312A - not authorized to make this transfer amount";

Basically I am trying to take what ever value is returned from the withdraw method and use it in my other method which is located in another class. If the withdraw method returns a value less then 0, the errorDescription will take that value and print ERR2556B - insufficient funds.
The second class can not be extended if that is an option since its already being extended from another class.

Set up a get property in the class that has the withdraw method to return the balance and pass that into the class that has the error description method.

I don't do Java but the logic should be straight forward:

PHP Code:

// not sure if Java has properties like c#, back in the day when I used Java it was getter/setter methods
public double getBalance()
{
    return this.balance;
}

// pass that into your class that has error description 


Good luck;

Thank you i figured out what the problem was using another way. Thank you for your help though!

Cool, what did you do?

I called a get method from its parent class that has the same values returned.
Now all i have to do is remember how to convert my array implementation to ArrayList
