Question about enums and enhanced for

[Mihai Lita]

Hello,
I have the following code:

enum CoffeSize {
	BIG(8), HUGE(10), OVERWHELMING(16);
	
	CoffeSize(int ounces) {
		this.ounces = ounces;
	}
	private int ounces;
	public int getOunces() {
		return ounces;
	}
}

class Coffee {
	CoffeSize size;
	
	public static void main(String[] args) {
		Coffee drink1 = new Coffee();
		drink1.size = CoffeSize.BIG;
		
		Coffee drink2 = new Coffee();
		drink2.size = CoffeSize.OVERWHELMING;
		
		System.out.println(drink1.size.getOunces());
		for(CoffeSize cs: CoffeSize.values()) {
			System.out.println(cs + " " + cs.getOunces());
		}
	}
}

My first question is: does it matter that the

private int ounces;

statement is written after the constructor of the enum?
Second question: does the enhanced for automatically put "\n" after the end of each Sop ?

Thank you,
Mihai

No it doesn't matter, you can declare an variable after using it,

No, but it will allways go to the next line:
Terminate the current line by writing the line separator string. The line separator string is defined by the system property line.separator, and is not necessarily a single newline character ('\n').

Mihai, when you copy code from a book or some other source, please mention where you copied it from (QuoteYourSources). Isn't this from Head First Java? (I vaguely recognise it...).

[Mihai Lita]

it`s from KB SCJP exam.

Ah, the SCJP Study Guide, also called "K&B" after the names of the authors (Kathy Sierra and Bert Bates).

Thanks.
