Class, Method Help

I am having a problem with my debit function. Instead of printing "The person has insufficient funds", it just adds a negative to the account.

public class Bank {

double initialBalance;
    double credit;
	double debit;
	double balance;
	double amount;
	
	public Bank(double initialBalance) {
	if (initialBalance > 0.0){
		balance = initialBalance;
	}
	}
	
	public void credit(double amount){
		balance = balance + amount;	
	}
	
	public void debit(double amount){
	if (balance > (balance-amount)){
		balance = balance - amount;
	}
	else if (balance < (balance -  amount)){
		System.out.println("You have insufficient funds.");
	}
	}
	
	public double getBalance(){
		return balance;
		
	}
}

import java.util.Scanner;

public class Accounts {

public static void main(String[] args) {
	
	Bank Paul = new Bank(250);
	System.out.println("The balance of Paul's account is: " + Paul.getBalance());
	Bank Fred = new Bank(-5);
	System.out.println("The balance of Fred's account is: " + Fred.getBalance());
	
	Scanner input = new Scanner(System.in);
	
	double deposit;
	System.out.println("Please enter the amount to be transfered to Paul's account: ");
	deposit = input.nextDouble();
	Paul.credit(deposit);
	System.out.println("The current Balance for Paul after this deposit is: " + Paul.getBalance());
	
	System.out.println("Please enter the amount to be transfered to Fred's account: ");
	deposit = input.nextDouble();
	Fred.credit(deposit);
	System.out.println("The current Balance for Fred after this deposit is: " + Fred.getBalance());
	
	double withdrawl;
	System.out.println("Please enter the amount to be withdrawed from Paul's account: ");
	withdrawl = input.nextDouble();
	Paul.debit(withdrawl);
	System.out.println("The current Balance for Paul's account after this withdrawl is: " + Paul.getBalance());
	
	System.out.println("Please enter the amount to be withdrawed from Fred's account: ");
	withdrawl = input.nextDouble();
	Fred.debit(withdrawl);
	System.out.println("The current Balance for Fred's account after this withdrawl is: " + Fred.getBalance());
	}

}

Have a look at your method and its If condition

Do you think that the "If" will be evaluated to false in any case ??

And welcome to The Ranch!

What are you saying? elaborate for me.

Please describe exactly which conditions make that false. Please provide sample values that will make that false.

Hi Alvado,
You are saying that

"it just adds a negative to the account. "

It means the If condition

in your debit method is evaluating to true always. Can you find out why its being evaluated to true always.
Will you ever find a case where (balance > (balance-amount) will be false ??

Got my point ? there is a bug in your code which causing this trouble..

One suggestion: Also place a check in code so that user can't enter negative values as this is absurd to make transaction with negative values

Well i also used the if else Balance < (balance - amount). Wouldn't that do? This worked for me fine in C++, java on the other hand is a handful.

That's not what I asked.

Mathematically, exactly when will balance > (balance-amount) be false?

This worked for me fine in C++.

Highly unlikely.

Wow i feel like a fool, i see your point now. HAHAH, pardon my stupidity.

No problem. Glad the lightbulb finally popped on.

And don't feel bad. We've all been there--staring too long at something and just not seeing what's right in front of our faces. I've been doing this a long time and it still happens to me.

Thank you all for your support.
