Thread: How can I refer methods ??

Hello guys ..

first this is part of my code.. there are few mistakes and missing stuff but i am still working on it

private static boolean isNowOverdrawn() 
	{
		if ( dollars < 0 )
		{
		return true;
		}
	else
		{
		return false;
		}
	}
 
	private static void deposit(double amount) 
	{
 
			dollars += amount;
			// check to see if not overdrawn and update isNowOverdrawn variable
 
			JOptionPane.showInputDialog("Enter amount: $");
			if( amount < 0 )
		{
			JOptionPane.showMessageDialog(null, "It's overdrawn");		
		}
		else
		{
			return; // here I want to update the balance
		}
	}

the question is ..

- A void method called deposit that takes a double amount as a parameter. This amount will be added to the dollars in the account (and could of course influence whether it is now overdrawn or not).
- A Boolean method called isNowOverdrawn (with no parameters to it) that returns a true if the account is currently overdrawn and a false otherwise.
- A double returning method called balance (with no parameters to it) that returns the dollars now in the account.


I am a beginner programmer so please be patient with me ^^ ..
my Question is :

How can I refer one method to another ?
to clarify .. when I deposit money I have to check if it's overdrawn or not ? and then update the overdrawn .. ??
the deposit is method and the overdrawn is another one .. when I write ( return overdrawn ) i've error message said ( void method can not be return to void method )


anyone has a clue .. could help ..

Thanks

First, to call the method of isNowOverdrawn in deposit, you can do like this:

dollars += amount;
boolean res = isNowOverdrawn();
if (res == true){
... // is overdrawn
} else{
...
}

...

Second, form your words, I think the method of deposit is not a void method, it should be a double method.

Thanks for replying ..

Ok now if I want to get the deposit from the user and update the balance method ..

this is what i am stack in ..

how can I connect two methods together ??
