| * @assertion Execution of a switch statement of the form |
| * switch (e) { |
| * label11 … label1j1 case e1: s1 |
| * … |
| * labeln1 ..labelnjn case en: sn |
| * label(n+1)1 ..label(n+1)jn default: sn+1 |
| * } |
| * or the form |
| * switch (e) { |
| * label11 … label1j1 case e1: s1 |
| * … |
| * labeln1 ..labelnjn case en: sn |
| * } |
| * proceeds as follows: |
| * The statement var id = e; is evaluated, where id is a variable whose name is |
| * distinct from any other variable in the program. It is a compile time error |
| * if the value of e is not an instance of the same type as the constants |
| * e1 … en. |
| * Next, the case clause case e1: s1 is executed if it exists. If case e1: s1 |
| * does not exist, then if there is a default clause it is executed by |
| * executing sn+1. |
| * @description Checks that if a switch statement does not have any case |
| * clauses, the default clause is executed. |
