== Exceptions
|
|
|
|
If the ``++switch++`` parameter is an ``++Enum++`` and if all the constants of this enum are used in the ``++case++`` statements, then no ``++default++`` clause is expected.
|
|
|
|
|
|
Example:
|
|
|
|
----
|
|
public enum Day {
|
|
SUNDAY, MONDAY
|
|
}
|
|
...
|
|
switch(day) {
|
|
case SUNDAY:
|
|
doSomething();
|
|
break;
|
|
case MONDAY:
|
|
doSomethingElse();
|
|
break;
|
|
}
