== Noncompliant Code Example

Case 1, the code is syntactically correct but the behavior is not the expected one

----
switch (day) {
  case MONDAY:
  case TUESDAY:
  WEDNESDAY:   // instead of "case WEDNESDAY"
    doSomething();
    break;
  ...
}
----

Case 2, the code is correct and behaves as expected but is hardly readable 


----
switch (day) {
  case MONDAY:
    break;
  case TUESDAY:
    foo:for(i = 0 ; i < X ; i++) {
         /* ... */
        break foo;  // this break statement doesn't relate to the nesting case TUESDAY
         /* ... */
    }
    break;
    /* ... */
}

== Compliant Solution

Case 1

----
switch (day) {
  case MONDAY:
  case TUESDAY:
  case WEDNESDAY:
    doSomething();
    break;
  ...
}
----

Case 2

----
switch (day) {
  case MONDAY:
    break;
  case TUESDAY:
    compute(args); // put the content of the labelled "for" statement in a dedicated method
    break;

    /* ... */
}
