Khalid's Mock exam engine question

Here's one question I found in Khalid's mock exam engine, which according to me doesn't accept the correct answer.
Which statements concerning the switch statement are true?
1)All switch statements must have a default label
2)There must be exactly one label for each code segment in a switch statement
3)The keyword continue can never occur within the body of a switch statement
4)No case label may follow a default label within a single switch statement
5)A character literal can be used as a value for a case label
According to me 3 & 5 are correct. However the mock engine seems to think otherwise. Any comments?

Only 5 is correct ..see how one statment can have multiple labels...
This is an Example from Khalid

public class Seasons {
public static void main(String args[]) {
int monthNumber = 11;
switch(monthNumber) { // (1) Outer.
case 12: case 1: case 2:
System.out.println("Snow in the winter.");
break;
case 3: case 4: case 5:
System.out.println("Green grass in spring.");
break;
case 6: case 7: case 8:
System.out.println("Sunshine in the summer.");
break;
case 9: case 10: case 11: // (2)
switch(monthNumber) { // Nested switch (3) Inner.
case 10:
System.out.println("Halloween.");
break;
case 11:
System.out.println("Thanksgiving.");
break;
} // end nested switch
// Always printed for case labels 9, 10, 11
System.out.println("Yellow leaves in the fall."); // (4)
break;
default:
System.out.println(monthNumber + " is not a valid month.");
}
}
}

Hi Wali,
Please note that I did NOT select option 2 as the correct one. All I said was that to me, both options 3 & 5 seem correct. Option 3 states that the keyword continue can never occur within the body of a switch statement.

Why can't continue take place in switch block? I think continue can be place within switch like break. Is that true?

Switch block is like if block, we can write continue in it only when it is written in any loop like for {} or While{} loop etc.
Writing continue in a separate switch block doesn't mean anything.it will just give an error at compile time.
I think it will solve others doubts ,
Thanks,
DS

Option 3 is not correct, because it is possible to have a continue statement inside a switch statement. The catch is, there must be some other structure like a while or for statement, which the continue refers to:
<code><pre> while (condition) {
switch (getValue()) {
case 1:
method1();
break;
case 2:
continue;
default:
method2();
}
method3();
}</pre></code>
The continue statement is inside a switch statement, but does not refer to it - it refers to the while loop instead. I know that isn't the situation that first comes to mind when we talk of a "continue inside a switch statement", but option 3 does say never after all, so we must be careful to consider all possibilities before we say it's true.

Hi Jim,
Thanks for replying. Yes you are right.
Just a few days ago I recall having read in JLS that a compile-time error occurs if continue appears in a switch statement. So when I saw this particular question I jumped to the conclusion without thinking about a nested for/while loop possibilty. Hmm gotta be careful in the future!
