switch and enums

[Andrei Nistor]

i have an enum define like
enum Day { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY};

i tried to use it with switch like this:

1 switch (Day.FRIDAY) {
2 case Day.FRIDAY:
3 System.out.println("Friday!");
4 break;
5 }

I have an error at line 2 that says:
The enum constant Day.FRIDAY reference cannot be qualified in a case label.

My questionis why?
...i can use FRIDAY and it's ok!

Regards

Salut Andrei

try this :

Day day = Day.SUNDAY;
switch (day) {
    case Day.SUNDAY:
        System.out.println("Friday!")
        break;
    case :
 .........
}

Still not working that way...

I found something that says:

" It inherits the context from the type of the object in the switch() statement, and that cases can simply use unqualified names."

..but still fog ... i think this is strange behavior on case-enums.

When testing an enum in a switch statement, you don't prefix the values in the case clauses with the name of the enum. The switch statement already knows that you are testing for enum values. So the code should read:

Day day = Day.SUNDAY;
switch (day) {
case SUNDAY: System.out.println("Friday!");
break;
}
