Help: a question about the Enum......

Question

Hi,
Now I defined a Enum like below:
public enum Seasons {  
winter， spring， summer， fall  
}  and here below is testing code
System.out.println(Seasons.winter);  the console will print 0.
Now I have a variable, its value is 2, so it should be mapping to Seasons.summer
int idx = 2;but how to write the code to get the Seasons.summer?

Answer 1

you can't (easily)
and you shouldn't
the whole point is that enumerations are abstract; you shouldn't be able to use them like integers and do arithmetic on them
what are you doing that will require this?
if you really wanted to, the Class class has a method called getEnumConstants() which returns an array of the enum objects in order of their ordinal value; so you could do something like
Seasons.class.getEnumConstants()[2]Edited by: spoon_ on Dec 18, 2007 2:11 AM
