enum CoffeeSize {
// 8, 10 & 16 are passed to the constructor
BIG(8), HUGE(10), OVERWHELMING(16);
CoffeeSize(int ounces) { // constructor
this.ounces = ounces;
}
private int ounces; // an instance variable
public int getOunces() {
Declaring Enums (Exam Objectives 1.3 and 1.4) 63
64 Chapter 1: Declarations and Access Control
return ounces;
}
}
class Coffee {
CoffeeSize size; // each instance of Coffee has an enum
public static void main(String[] args) {
Coffee drink1 = new Coffee();
drink1.size = CoffeeSize.BIG;
Coffee drink2 = new Coffee();
drink2.size = CoffeeSize.OVERWHELMING;
System.out.println(drink1.size.getOunces()); // prints 8
for(CoffeeSize cs: CoffeeSize.values())
System.out.println(cs + " " + cs.getOunces());
}
}

Please explain the code..especially BIG(8), HUGE(10), OVERWHELMING(16);

Thanks
