Switch case

[Karu Raj]

By commenting out which of the following lines can you make the following class compile with no errors ?

 
class ZZY {
static void main ( String ka [ ] ) {
int obj = 34 ;
$first : // ---> line 1
System . out . println ( " In first ") ;
21 : // ---> line 2
System . out . println ( " In 21 ") ;
_89 : // ---> line 3
System . out . println ( " In 89 ") ;
obj : // ---> line 4
System . out . println ( " In obj ") ;
}
}

line 1
line 2
line 3
line 4

Answer is Line 2

Hi,

I think the question is not about switch statement...it is about valid labels.
21: is not a valid label. A label should be a valid identifier.
21 is not a valid identifier.
Correct me if i am wrong.
Thanks.

Hey Karthik ,

I think Putti is on the right track. Instead of just giving you the answer right away, we kind of like to see if we can help you figure it out yourself! So, I was just asking you a question to help you figure out the problem.
