== Compliant Solution
----
switch (param) {
case 0:
doSomething();
break;
case 1:
doSomethingElse();
break;
default:
error();
break;
}
----
== 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;
}
