== Noncompliant Code Example

----
switch (param) {  //missing default clause
  case 0:
    doSomething();
    break;
  case 1:
    doSomethingElse();
    break;
}

switch (param) {
  default: // default clause should be the last one
    error();
    break;
  case 0:
    doSomething();
    break;
  case 1:
    doSomethingElse();
    break;
}
----

== 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;
}
