Code:
	public static void main(String[] args) 
	{
		double runningBalance = 0;
		
		blah(runningBalance);
		
		System.out.println(runningBalance);

	}

	private static void blah(double runningBalance) 
	{
		runningBalance += 8;
		
	}
Hi guys,

Just a basic question on why running balance doesn't show 8 after I update it? Is this not allowed in Java? Apologize for such a newbie question, but I couldn't find examples to achieve what I want.

Thanks
