Java enums

Let us see another example of Java enum where we are using value(), valueOf(), and ordinal() methods of Java enum.

1. class EnumExample1{  
2. //defining enum within class  
3. public enum Season { WINTER, SPRING, SUMMER, FALL }  
4. //creating the main method  
5. public static void main(String[] args) {  
6. //printing all enum  
7. for (Season s : Season.values()){  
8. System.out.println(s);  
9. }  
10. System.out.println("Value of WINTER is: "+Season.valueOf("WINTER"));  
11. System.out.println("Index of WINTER is: "+Season.valueOf("WINTER").ordinal());  
12. System.out.println("Index of SUMMER is: "+Season.valueOf("SUMMER").ordinal());  
13.   
14. }}  

Output:

WINTER
SPRING
SUMMER
FALL
Value of WINTER is: WINTER
Index of WINTER is: 0
Index of SUMMER is: 2
